Super Stock wheel arches.

This is a 30.60” tire. The front of the tub will leave you about 1” clearance. I’d suggest to confirm with a measurement. Then fold the lip over onto it and attach. Also check the inside of the tub to ensure adequate space at the tread edge ( by the spring box). I trimmed / raised my tub lip at that area. It’s lots of work to make them nice but the results are worth it.
