Hey, Steve,
Sorry for the late reply - was on vacation when you posted the pics and I didn't have reliable web access...
The Hotchkiss parts look sweet, but the thru-bolt or stud replacement is taller than I visualized. The price is also 2x what I was hoping to spend, but that's on par for my project. Back when I started my mess in 2001, my costs were:
Test wheel - $50
Bare Cobra wheels - $300 (shipped from Austin)
1" Billet adapters - $100/pr
Machine work - $75
Options have improved quite a bit since I started going down this road, and that's a good thing!
