I'm doing a disc swap and front end rebuild, which swaps me to BBP and requires new rims and tires. Here's what I'm looking at:

225/60R15 on 15x7 rims

Here's my question:

What kind of backspacing might this require ('71 Dart Swinger with '74 disc parts up front, 7.25 with 10" drums out back)? And with that said, what length studs should I look at installing (the current studs extend 1" beyond the drum/rotor hub)?

Thanks for the help!

It's not rocket science, we're just splitting atoms.

Stock studs should be fine if the backspacing is stock and no adaptors were used.

Backspacing is about 4.25" to 4.5" depending on style of rim and application/rim width.

Thanks D.I.

I'll test fit everything with stock studs and go from there.
