My Lord, Its like I'm retarded.
15' Cragars, 4.5' wide with 2 1/4' back spacing. Yes, I am looking to run narrow tires that are highway safe. Radial for sure. Sorry for all the vague and scattered post's!
I've run 215/65s and 205/75s on my 68. Both fit fine. The wheel I used was a stock 15" steelie- 5.5" wide if I remember correctly, but don't quote me on that.
