8 3/4 vs. 7 1/4 brake question

[firefighter1]

I'm planning on swapping out my 7.25 with a 8.75 rear end. But in order to prepare for the swap I have a quick question.... Are all 8.75 rear ends brakes big bolt patterns or are they small bolt patterns as well? I am trying to see if ill need to replace my Boyd Cottington wheels after I swap out the rears end. Thanks guys!

A-body 8 3/4 all came with small bolt 5 on 4" bolt circle. Every other Mopar 8 3/4 are 5 on 4 1/2" bolt circle.
Oh and by the way I'm a retired Fireman.

Thanks for the info. I guess it's a good thing that the 8 3/4 I'm getting is out of another A body mopar!

Doesn't mean that someone didn't swap out the small bolt axels for big bolt pattern. Check the size before you commit just to be sure, you never know.
