I see why you put on the wheels backwards. Will you eventually get wheels with the correct offset? Yeah, wheel/tire fitting can be a bitch on older muscle cars regardless of if they were Fords, Chevys, etc. I had to trim a few rear quarters, sometimes both in front of and in back of large diameter slicks, without messing up the painted 'lip' and making the cuts look good. Hated to cut OEM sheetmetal but that's racing!
