The only way you can use that backspace is with a narrowed rear. Otherwise you need either 5" or 5.5" like the wheels I posted earlier.I have TCI street/strip 4-link under 63 Nova. I contacted TCI (Evan Daley) and he said on rear to use 17" rims 8" wide with 255/40/17 tires (tires 10" wide mounted). He said rims MUST have 4.25" back spacing. Jim Reeves
1) what's the maximum rear tire width I can fit in the stock tubs?
2) what rim offset would I need to get that max width?
3) what flange-to-flange dimension is needed (if I'm cutting/re-splining a 9" to fit)?
