Thanks for all the great replys, and the pictures. I'm getting a lot of good advice, and really appreciate it. Sounds like 29-30" for the rears seems to be the concensus.
I studied a lot of cars at the AutoRama in town here last month, and one of the things I noticed was that the wheels seemed a little small compared to the overall tire size, so I'm thinking for sure 16" and possibly 17" with a 30" overall diameter?
I keep looking at all kinds of different options. as far as wheels, either American Racing Torque Thrust D's or American Racing Salt flat's.
What do you think? Trying to go with something that copies the look of the 60's.
