1970-73 Challenger rear Backing plates
The parking brakes strut lever on the 10" brakes is different between A body and e-body...
The a-body has a bend in it to accomodate the narrower shoes, where the e-body lever is flat....
I'm not sure about the backing plates...
The other thought that comes to mind is can you put an e-body set-up on an a-body??? If the strut plate lever is flat for the e-bodies does will it fit on an a-body??? I have never compared the dimension from the backing plate to the back of the flange on the axle to see if it is different between the two bodies... If the flange to backing plate clearance is different, they you may not be able to put e-body brakes on the a-body...
