I'm having trouble getting the correct info on rear wheel offset for a 1970 Superbee with a 8-3/4" rear end with upgraded disk brakes (1/2" overall addition to length). I would like to purchase the reasonable icon rr625 15x8 wheels with a 3-3/4 offset planning to run 245/60/R15 tires on back with 15x7 225/60/R15's up front. I've noticed most steel wheels from that period in 15" have 4" or greater offset and with the loss of 1/4" on both sides I want to verify prior to purchase. I'm working 1200 miles from my car so please don't tell me to measure it:)Thanks
