I have a 64 with a 2/4 on mine and it sits pretty nice. little tuff getting rear tire out from under fender, cause those new coils have little stretch. Had to put p245 tires on it 255's rubbed. You prob need to check into the backspacing before you buy aset of wheels if you want some wider meat, wish I had. trim some off of wheel well inside lip might give you another inch. I also have the 72 rearend under it, not sure bout spec diff in the two. It was a direct bolt in but not sure if its same width, im asume it is.
