After Market 4.5 inch A-body 8.75 Rear Drums?

Rocket said
Just wanted to double check people's experience once again with 4.5" brake drums. I am not sure the combination I want to run is covered in the thread.

I have SBP 8 3/4 axles drilled to the 4.5 bolt pattern. I also have a set of E Body 2.5" backing plates for 10" drums. Can I use this combination with a 10" E Body drum for 2.5" brake pads or will there be interference issues with this drum / backing plate combo using the SBP drilled axles? If there is minor interference can it be machined out of the lip of the drum or backing plate?

Thanks

The difference is in the dish of the backing plates. If you use B or E body backing plates you can use B or E body drums. I decided to use B body backing plates and drums ('72 Charger) on my '66 Valiant because of parts availability. Getting bigger brakes in the bargain is icing on the cake.
