General question. If I swap backing plates and hardware will it change diff width. Like going from a 1.75 to 2 or 3 inch drum. I’m trying to change to an easier to get drum. Don’t want rear disk. The front is 11 inch disk. Craig
 
I believe BUT do not know for fact, the backing plates will have the depth compensation if you were to go from 10 x 1.75 to 10 x 2 etc. so the overall width will not change


Note: there is a spacing difference from bearing to wheel mounting flange from real A body axles vs cut down B,C,E body axles

Not swapping axles only brake stuff.
 
You didn't mention if you have large bolt pattern axles now. If not, you have to swap axles to big bolt pattern which are longer and have a different register to compensate for the larger drums.

I understand, I was only pointing out because if you take brakes from a B or E body for instance and put them on an A-body housing with A-body axles there might be a dimensional mismatch due to the axle spacing (wheel mounting flange to bearing #1) As I understand it the A-body axle has a shorter dimension (#1) than the other body axles.
