Greetings -
I've been all over looking for some details on how I can reverse engineer/copy/DIY a set for myself.

Tony (aka marines2060) posted a few pics on the GEN3 section showing the mods he made to the rear alignment bars to accommodate the new engine/exhaust.

How do the front bars work/attach? I'm guessing they cantilever forward and are attached to the long chassis runs on each side. Are they then supported with a screw-jack to the floor/ground to level and prevent droop?

Here is my cheezy pic of what I guess - but if anyone has a pic of the real thing - in action - or a dimensioned drawing - that would be real helpful.

TIA - Cheers - Jim

your picture is almost right. There are no screw jacks. The frame has a bracket that extends down the upper frame rail and a pin is placed under the bottom side of the frame rail. Basically the alignment bar is cantilevered from the top frame rail with a stop the but up to the front edge. Also the alignment bar is on the inside of the body pins.

Bob - Thanks for that!

I'm guessing 1" steel stock? My crummy sketch was "meant" to be inside the body pins -- oops.

the upper frame rail and a pin is placed under the bottom side of the frame rail

Is that "down" strut just ahead of the front suspension - I'd guess--and tied into the lower frame rails? - Or, is all the rig secured to the upper frame rail?

Sorry for the follow-up - don't want to send some more steel to the scrap heap!
[Actually looking at building out of 8020 aluminum stock and bits!]

Cheers - and thanks! Jim

The alignment tool hangs off the upper frame rails only. Also you will need to make something to secure the steering shaft. I use a piece of "C" channel that pins into the upper frame rails and a shaft that locks into one of the steering shaft adjustment bolt holes. This keeps the streering locked straight when making toe adjustments.

Bob - would you have a picture of the steering lock you use. I think that's a problem for all of us. Thank you

Thanks Bob!

I'll look forward to seeing that steering lock tool - I was thinking "Vice Grip."

Cheers - Jim

To center and lock the steering, I have a Home Depot 3/4" square aluminum tube that lays across the inner frame rails above the steering column, with a vertical, long bolt (4-5") that passes through the aluminum tube and into one of the unoccupied holes in the steering shaft. The bolt should match the size used on the shaft itself, just longer.

Way better than VGs!



Cheers - Jim

Here are a few pictures of how mine attach to the front.
