Hot Rod 38 Plymouth custom panel fabrication

 by kustombitz on 04 Dec 2018 |
No Comment
We have put a lot of time and effort into this 38 Plymouth.  The whole rear lower panel and floor right through to under the seat has been completely hand fabricated and replaced.  The front and rear mud guards have been widened and the shape reworked for cleaner lines, the guard edge now follows the wheel's shape and shall feature a straight edge running board.to clean up those ugly Plymouth bits but still retain some typically Plymouth features like the swage lines. We have basically just fattened it up and made it more curvey.

38 Plymouth hand formed rear roll pan rust repair

With the rear floor done and the back seat panel finished it was time to roll up a new rear tail pan on the 38 Plymouth.  It certainly was not easy, a complex compound curve with a dead flat bottom and a double swage line through it and a pair of exhaust slots.  It has come up well though.

38 Plymouth sedan new custom tailored boot floor and inner tail pan

The 38 Plymouth has a Jag diff and aftermarket 32 Ford fuel tank so the old rusty floor had been removed.  To give the floor some strength I went with deep ribs because there was no frame under the floor and not room for a frame between the chassis mounted fuel tank and the floor.  The step down at the back drops down to line up with the bottom of the rear sill panel to box it in and make it resistant to body flex once its all welded in.  This was all formed in one piece, how ever to install it the rear sill panel was cut out, it was all rusted through anyway and required a custom formed piece too.

Electric Wipers for the 38 Plymouth project - New Port Engineering

 by kustombitz on 09 Jun 2016 |

The Australian models of the 38 Plymouth [and dodge] had the wipers down on the bottom of the windscreen and service parts just dont exist, not to mention they are fairly flimsy anyway and well worn and rusted by now.  The solution was to fit this electric wiper kit from New Port Engineering to the top of the windscreen like they were on the US models.  However the Aussie body has some differences in the top of the windscreen that mean the holes have to sit higher for the meachanism to clear on the inside, so you can't use their template supplied otherwise you end up wiith holes that you need to fill again. Apart from that these New Port Engineering wiper kits are very well made and the new wiper arms look the ducks nuts.

8:71 Supercharger install on 454ci powered '55 Chevy

by kustombitz on 30 May 2022
You would think a supercharger kit install would be pretty simple .... well no, is the short answer. A wise man once told me a 'kit' is not a solution.  And having worked on a few of these set ups now these words keep ringing in my head and I remember this old man who at the time I didn't think was that wise at all .... now I am older and I see.   In this install I had to port match the heads to the intake as there was a substantial lip into the head port because of the large intake manifold ports. If not corrected would have led to fuel puddling and fouled plugs and drivability problems that would have been hard to diagnose once assembled.  Also the distributor hole at the back of the manifold was off centre and way too big for a standard chevy dizzy and any aftermarket dizzy too. So I had to make a boss to take up the slack and provide a stable boss for the dizzy clamp to work properly.   To add to the woes, the engine assembler failed to pick up that it was a tall deck block and required a longer oil pump drive shaft .... that was hard to diagnose when a new engine loses oil pressure for no reason.   I got there in the end with modded accelerator links, better fuel line route, boost referenced carburettors and a proper harmonic balancer for a blower application.  The install was challenging on this one but the end result was a sweet running engine with monster amounts of torque to hall this heavy full size sedan around the hills .... and cool looks of course.  

41 Willys Coupe Gasser Chassis

by kustombitz on 30 May 2022
41 Willy Coupe chassis fabricated to original dimensions yet extra strength provided in the depth of the chassis and via tubular centre X member and many tubular cross members to take the weight and torque of a big block Ford drive line.  This chassis will have an original steel body fitted to it and the owner wants the whole car to resemble an early 60s drag car, right down to the rear radius rods that look like ladder bars, however it has to have nice street manners and pass ASRF construction guidelines for safe street rod engineering.  Now many may argue a leaf sprung front end and rear end is not the best handling street car and I would agree, but there are always trade offs for the look you want and the right combination of parts installed with the correct geometry can still yield a very nice driver with a really cool look.  When driven responsibly this 41 Willys will provide hours of enjoyment for the owner cruising around.   Chassis by Kustom Bitz [our custom designed rails], Engine Ford Hemi V8, T400 auto, 9" diff installed on leaf springs with diff housing floaters designed by Kustom Bitz for street use [so we have flexibility and suspension give], Super Bell front I beam with disc brakes cleverly mounted to parallel leaf springs without any mods to I beam and not relying on welded parts.   See our section on Hot Rod Chassis construction for more images of our various Willys Coupe chassis that Kustom Bitz has built.  

'67 Toyota Crown Ute - another air ride bagged project

by kustombitz on 01 Apr 2021
The Toyota Crown ute is progressing along, the body is fitting the modified original chassis and this is how it will look when it's dropped ... I think it has the right stance ... The framing you can see is holding the upper body together as the floor and lower sections are rusted away and have been cut out, then to be completely refabbed by us.  The frame allows us to lift the body on and off as we please during this stage.

1940 Ford Coupe chassis BBC 454 L80E 9" and air ride

by kustombitz on 01 Apr 2021
Kustom Bitz just completed a 35-41 chassis, stepped up at the rear and a reversed centre X member allow this chassis to sit 40mm off the deck. It runs a Rod Tech IFS, big block chevy and L80E auto, a 9 inch diff with floating hubs, all on modified original rails. Kustom Bitz has developed our own boxing plates that suit the original rails near on perfectly. Original Ford rails are curved from front to back there are no straight sections, so to get something that fits right we had to jig the chassis up and map them out.  This is what we do, when it just needs to be done right to make it a well engineered car.  This allowed us to make a nice transistion for a high step at the rear. We have designed in 6 inches of travel at the back, so this car can have a normal, almost stock ride height then dumped to the max when parked.

LS Engine swap and custom air bag IFS

by kustombitz on 19 Feb 2020
'67 Toyota Crown ute chassis build is going well. Got the LS engine and 6 speed manual box in place and we can use all the orginal serpentine pulleys, brackets etc. The narrow wheel track on the Toyota called for a tailored solution when it came to the front end.  These old Toyotas dont have service parts available any more so the front end had to be changed, so that made a brake upgrade alot easier too. We run R6 air bags from Air Ride sitting at a ride height of 6" for the air bag so got plenty of air volume in them for a good ride quality and a full length travel shock absorber so we get proper rebound tuning, along with a power steering rack.  So at the sill [belly of the car] we get a 5" ride hieght with a 4 inch drop, this thing will look great.

Double shear brackets - rear coil overs Hot Rod Chassis

by kustombitz on 30 May 2019
Recently in Victoria some engineers have called for the upper and lower mounts for the rear coil over shockers to be a double shear bracket.  The thoery is that the bolt has too much twisting force on it and it will break. Well thats why on Hot Rods we use a 5/8" grade 8 bolt in a single shear bracket application to over engineer it so it does not break. A typical OEM application uses a 1/2" bolt in a double shear bracket. However to please the engineer we have thought out a simple plate kit that can be welded in on the upper mounts as you see here to satisfy their requirements and should fit into most applications without too much effort or rework.  We have a lower mount bracket nutted out as well.

Diff bump stops custom made

by kustombitz on 08 Mar 2019
So many hot rod shops don't install proper bump stops.  In this instance we had to rebuild the shocker mounts on the diff as the rear end was bottoming out on the shocker travel becasue it had no properly designed bump stops in place. So the shock absorber mounting bracket was absorbing every bump when the suspension bottomed out, easy to see why both mounts broke. While we were repairing the diff I made a simple yet effective progressive bump stop that is held in place via the U bolts that hold the diff to the leaf springs. It turned out a very successful set up. This is yet another example how Kustom Bitz can sort out problems on your custom car or hot rod, its what we do.

Torana A9X custom made rear pan hard bar 9" Diff

by kustombitz on 08 Mar 2019
Back in the day Group C racing one of the tricks to get the Holden Torana to handle nice and be more predictable in corners was to fit a rear pan hard bar to give much better diff locating than the OEM triangulated 4 bars offered.  However the body, subframe and floor pan at the rear is no where near strong enoungh to concentrate the loads of pan hard bar in any one spot, so it has to be carefully planned and constructed, especially so in a street car like this that we cannot put a full roll cage in. You see in a race car I can place the roll cage in a position to pick up such loads placed on the pan hard bar brackets, but in this situaton we couldn't. The picture above is with the unit installed, keep in mind the car was just a shell so no weight was in it and the rear is sitting high. Once the full wieght of the car is on, it will sit fairly level.  It retains the original triangulated 4 bars however we run PU bushes in the bottom arms and ordinary rubber in the top arms. So the lower arms and pan hard bar do the locating and the top arms have some give so they don't bind with the pan hard bar.

Our first wheels up Launch in Vintage Gas drag racing

by kustombitz on 27 Aug 2018
First pass for the day in Q1 in Vintage Gas [V/Gas] and we did our first wheels up launch in "Angas" and later in the day ran our best time so far with this combo with an 8.80s for the 1/8th mile track with an ET of 79mph.  The venue was Sunset Dragway which is just outside Mildura in country VIC. It was a 20deg sunny spring day with little wind, an all but perfect day for this time of year.  Great facilities at this venue for grass roots racers like us and they really looked after all of us racers, so its well worth the trip we had a blast. As far as our little 105e Anglia Gasser goes there is still heaps in it yet when a few tech issues get sorted out, but totally stoked at the moment. woo whooo .....
