I am rebuilding a 68 firebird, and upgrading to a Moser 12 bolt rear end, with a SSBC disc upgrade. I think the rear rims will take a 4.5 inch backspace, but the front SSBC disc setup with 2 inch drop spindles has created a problem trying to get the correct offset. My guess would be a 3.5 inch backspacing with a 7 inch rim. If anybody has come across this problem and could give some advice, it would be much appreciated.
