I haven't built one yet, but I, too, am working on a 68 convertible and need to build a jig to keep it in spec. I have looked all over the web and I've seen a few.

This first one sells for around $600, but I'm not too sure it looks like it would actually keep the front and rear of the car actually lined up too well. The front and rear supports aren't attached to the center section at all. One feature I like about it is the way it also attaches to the door hinge mounts. This might be handy if you're replacing the entire front end.

This second one is one that I found online doing a search. It seems really solid.

I think I will be fashioning mine from this last design. I found it on a restoration company's website. It seems really sturdy. It mounts at the front frame rail, shock tower UCA mounts, and the front and rear of the leaf springs. I may include some supports at the door hinge mounts similar to the first design above.

I will be getting the steel for it on Monday or Tuesday. I'm not too sure how soon I'll start on it though because it's really cold in my garage.

No, but I sure wish I did. It would make it easier to build one if I did.

I've begun making up my construction plans and I have some preliminary length and width measurements, but I have yet to actually determine the support placements.

I think I replied to one of your previous posts about frame measurements. Those plans state that there is a + or - tolerance of .06 inches in the measurements. That's hard to measure with a ruler, so I converted the inches measurements into millimeters and the just rounded off the results. I end up being within .01 or .02 of an inch of the stated dimensions.

I plan on using a plumb-bob to determine exactly where the car supports will be placed on the jig.

It all seems like a whole bunch of time and trouble, but I just want to make sure that my car comes out as close to perfect as I can get it. And I also figure that I can use this thing mltiple times (you can read that as 'I will want to buy more cars!!' -- of course SWMBO willing ;) )
