68' dana 60 in 1971 Charger. How big a tire will it take?

[migsBIG]

Hi all, been awhile since I've been on here. Hope to see a few familiar faces on here.

Have a question. Have a 1968 dana 60 rearend from a charger and the spring purches have been cut and have chevy mounts in it (yuk). Since the perches are going to get removed, figured it would go into a nice 1971 Charger project in the back. WOn't be happening for a while yet, so just trying to get an isea what size of rims I need to be getting for it. Looking to but alot of rubber back there even for a street car.

If anybody has done this conversion, please let me know what size rim/tires you have gotten in there.
