Hi, will these fit my '70 with BFG Drag Radials 275/50/15?

Offset is -25mm, is that too much? I believe my current ones are 12mm but I'm not sure :-/

Also, what is backspacing and what is the bolt pattern on the Chevelle? 5x4.75"?

Thanks :)

No you need the 4.5" backspacing not the 5.5 backspacing.

Thanks for that. I was just looking at these (can get a good deal) but the guy says they're 3.75" BS. For an 8" wheel that gives a positive offset, right?

Will these fit and is that offset bad?
