Body Alignment

[JEFF GHILANI]

Hey guys, Charley suggested I start a thread when I asked him whether it was OK to post this.

I have been meaning to get this pet project done for about 20 years now and finally got around to it. I figured I would post it here because no group understands these cars better and it is a good discussion topic.

I’m offering a toolset online for body alignment of full chassis GM cars that mimic and improve upon the tools used at the factory. They utilize the original chassis and body location-controlled alignment holes used at the factories, eliminating measurements and spacer block setup from symmetrical but less dimensionally controlled features. It also allows alignment while the body is still safely away from the chassis so that you can join the units without worrying about collision of pinch welds and damage to other nested geometry.

Factory photos show these alignment locations being used, but oddly, I’ve never seen these holes referenced in service literature. Some assembly manuals do refer to them vaguely if you’re looking for them.

Also, I’ve never seen an old Kent Moore version of this. Maybe one of you guys has. It’s a little beyond service, but you’d think collision repair and frame alignment shops could’ve used this.

I’ve located these alignment holes in different locations on almost all GM cars from 1955-1996. They change character but they are exactly where they should be in every case.
GM changed the stepped diameter geometry and locations depending on platform and generation, so right now, 1968-1977 GM “A” Body is all I have available. I’ll offer more applications if these sell well enough.

There is something on the market for subframe cars, but it doesn’t actually do the alignment job correctly.
I have something coming for that as well.
And some other items.

I’m interested in your comments.
