67-69 barracuda front tire width
Wow!!! That's very close to what I am working with. 15x7 fifth ave steelies, 73 up disc brakes w corboba big brake conversion. I was looking at 205 60 R15s and 215 60 R15s. Do you have a nice sideview pic mostly of the fender and rim w tire on it so I can get an idea what a 205 65 R15 looks like, and how it fills the fenderwell.
I have a worn out 255 60 as a mockup tire and wheel on a 15x7. I threw it on there with the car on jacks , dropped all torsion bar tension and lifted the LCA to an approximate ride height. Ran steering left and right lock to lock. It hits the fender in the front with a worn out 255 60, so I know I need to go smaller tire size in the front.
