70 Dart, welds, Mickey ET streets. Tight fit!

A-body 8 3/4 with big bolt pattern axles? 15x8's?

Yeah the section width can vary by a lot from one manufacturer to the next, makes a big difference when you're getting down to the last little bit for clearance. 1/4" is pretty tight to the springs for that much sidewall, you should have a little room to the quarter so if it ends up rubbing on the springs you might try a 1/8" spacer.

Yea that's what I was thinking, like I said, just didn't know with the spacer it I'd have enough thread on three studs to be safe.
