For anyone following this or who wants to mount rims designed for a corvette: I finally got this to work. The wheels and tires are on. For the front I ended up using the stock studs (48.5mm length, 14.23mm knurl diameter, ~ 7.7mm knurl length), a 5/16 (7.9375mm) spacer and adjusted the wheel camber approximately +1 degree. This seems to be working nicely. The rears required no modifications.
There are two major drawbacks... I am probably at the bare minimum stud thread available to bolt onto. The lug is getting about 7-8 threads. I'll obviously keep close watch on it. The other is tire wear, with the positive camber the front tires will wear unevenly to the outside.
Would I recommend this to anyone else?
If you have a set of wheels from your Vette you paid ~6k for, and you're an idiot like me... then yes, by all means, give it a go. If you are completely sane and don't already own the rims, I recommend buying something that just bolts right on.
