Were all 8 1/4" rears large bolt pattern?

I believe most of them were scrapped when the carriers wore out and the spyders broke. And those who didn't go 8 3/4 bought them all up. I have 8 3/4 housings we cut what we need.

8 1/4's ciunked when backing them off the car carrier when they were new. probably not many left that are worth fixing.
