'64 Dart Cragar S/S Size & Back-spacing

I think the new runs on the sbp 15s are a lrger offset. i recall mine are like 4 3/8? I need to measure to make sure. But the newer 15s will sit in for more tire clearance on the outer edges.

What I found out was they are 3.5" offset. I have a 15X7, 4" offset with a 235/60 on the back of my 64 and they run too close to the fender lip
