Rear End Swap 7-1/4" to 8-1/4"

I Did the same but I am Having a problem that the brake pads that I ordered are too big. I dont know what is happening. The pads and the Drums are of 2 1/2 in. Does yours take the same or are they 2". This Is driving me crazy. I got a diff that only had the back plates and I guess that is why I am having the problem of finding the right ones.I ordered the same for a 1973 Dodge Dart Sport and Advance says that the 2 1/2 in are the right ones. Help

If it's an 8-1/4 it's most likely 10X2-1/2" which would take shoes 2-1/2" wide. Take a measurement to check the shoe width, if it is 2-1/2" wide chances are it's the right one. Also set it inside the drum and see if the arc of the shoe matches your 10" drum. When my duster ran drums on all four corners it was always a hassle to get brakes, the shoes were the wrong width or the wheel cylinders were the wrong size. Are you sure they did not stick you with 7-1/4" back plates, they may bolt up but are only good for the smaller brakes. Check the air gap between the back plate and the drum, if it's a big gap chances are they are the wrong backing plates. Getting mopar parts can be a royal pain...

Never heard of an 8-1/4" with anything smaller than 10X2-1/2" drums. If anyone knows different please chime in.
