8 3/4 swap questions...

He has a 74 big bolt 7.25. It should have 10x2-1/2" brakes.

10x1.75 and smaller was small bolt only, if memory serves...

Oops, sorry!, totally right. Misread that one. Yes he should have the right backing plates and hardware

and yes you’re also right, 10 x1.75 was small bolt 8 3/4”. Small bolt 7 1/4” usually got 9”
