73 Dart Swinger Resto-mod

Thanks for the heads up on the backspace. It came with 225/70R14s in the rear, not sure how wide the rim is. I have about 1/2" clearance to the spring and about 1.5" clearance to the fender, so I have more room to grow outboard than inboard. Problem is, decent looking 15x8s with 4" back space are not coming up on Jegs or Summit. I could run the cheapo Cragar "soft 8" steel wheels, but those look lousy on the street. I have no problem swapping them on at the track, though. Trying to keep things decent and low-buck, I was hoping to run these:

Maybe I can get away with a 1/2" spacer?
