My 50 is a Canadian one built in Oshawa, so the wheels may be a little different. My stock rims did not clear the 12" rotors/calipers from the CPP conversion kit, so I've gone with a set of Wheelsmith smoothies. Only problem - there may be a problem with the repro hub caps not fitting the new rims.
Went with about a 3 3/4" offset and a 14"+ barrel diameter for the 16" rims. I also converted to tapered roller bearings as well.
