A few questions, on possibility of upgrading a '71 Dana 60 12x2.5 brake to 13 inch drums. Thinking of two/three possibilities while keeping stock axles:
1). We're their Dana 60 applications that used 13" drums which can be switched to '71; and

2). Can Dana 70 13" brakes be switch, all from backing plate out. Maybe 80s Suburbans?

3). Other option, e.g. 70s Fords 3/4 ton that used 12x3 brake shoes, chevy dually brakes



Thanks,
Les
My rear axle is a Corp 10.5 14 bolt. Much different than Dana rear axle. Not sure what all can be swapped in the Dana rear axle world as I've never messed with them other than just maintenence work.
