You basically have two options here as well: 1) flip the center and do a custom backspace between 3.5" - 4.5", or 2) run at least a 1.25" spacer. How much depends on which rear end you have (earlier pre 69 rear, or 1.5" wider 69-up rear).
I appreciate this info. I have a machine shop that said if I bring them my hub they will measure it and center bore my wheels. I have a spacer kit, that I can use for the rear if need be. Or may just sale my set and run my stock steelies that i have and not have any issues.
