Hey, just saw your message on my visitor page, thank you, that's a beautiful car you've got there. To answer your question, the wheels on my '68 are Vintage Wheel Works V45's, 17x8 with 4.5" backspacing in front, and 17x9.5 with 5.5" backspacing in the rear. Tires are BFG KDW's, 235/45/17 in front and 275/40/17 in back. I think 4.75" backspacing would be better in front and allow me to run 245/45/17 tires, which would have the identical sidewall height to the back, but this works fine the way it is.
