Advice On Wheels.....

I think it will depends on the size of the cragars you get. (backspacing ect). I think 5x4 are hard to find. I have a 69 Signet with the 70s Cragars and BF Goodrich tires. The rims are 7" wide...can't remember the backspacing, but were concidered a deep dish.
Front P125/60R/14
Rear P145/60R/14 (As wide as I could go) but you have a higher wheel well fender)
