Thanks for all you help.
I accidently found the car i was looking for in the Hurst catalog. It's a bitchin '67 on p.48 (go to mrgasket.com for that catalog). I e-mailed their tech guys for more info but they didn't seem to eager to help. I should have told them i also wanted to buy a shifter!!!
I think those adapters might be the best way to go. I'm also looking into that '96 hotrod mag. By the way, i live near the SLP camaro shop in LaSalle, Quebec. I can get those ZR-1 wheels for a local speed shop that deals with them.
