I tried the 5.60.15's on my little grey 70 last spring and found they were just too short. Really looked too small IMO. I later went with the 6.40.15 Firestones and think I nailed the look with the Cragar's and 640's on it prior to selling the car. I didn't like the big rubber cut on the inside profile of the Pro Trac either. Here are the Coker Firestones.
