Crager SS 15x7 front 15x7 rear 68 barracuda.

Im looking at the cooper cobra tires. Seams like 215 65 15 are my only option. I currently have 215 70 14 on original Steelies that I think are 5.5 not sure on BS , but I have no rubbing issues..
The 215’s are one good inch taller than 205/70/14. Plus your rims will be 1/2 wider and the backspace not quite as much as oem. All this pushes it out and with the extr height the bottom fron corner is your concern. By putting the lower front fender brace in the position that pushes the fender out to the maximum on my old duster I had about 3/8" clearance from the tire to the fender with those Cragar’s and that size tire.
Apparently barracudas may even be tighter there. Some people lengthen the rod
