Just picked up a drum to drum 8.75" a body rear for a upcoming project and found the rear drums are something I have never seen. The have a huge flare out as it reaches the backing plate. If you set them flat on the floor with the backing plate side down the flare out must be at last 1.5" Is this some aftermarket stuff or something that was used by the factory. Does this help ID the year of the whole unit?

Yes, that's what A-body 8.75 drums SHOULD look like

No stamped in dates but if it's a clean one there could still be ink stamps on the axle tube and center section, these are assembly dates. There are other small physical year to year differences, brake likes, etc. post some good pics and I'll see what I can tell you.

Those drums were more often seen on Plymouths than Dodges, in fact RARELY seen on Dodges...

Does this help ID the year of the whole unit?
No Photo Yet, probably tomorrow.




My experiece has been that the flared drums were a 70-72, non flared 69 and down

I forget that small bolt continued on in drum brake cars.

I have seen flared drums on 68-69 Barracuda's. I used to call them Darth Vader drums...

I've only owned two A-Body's in my life and both were Dodge's.
Both had the flared 10x 1 3/4 drums.

I have had quite a few 'A' body 8 3/4" rears over the last 25 years and have only found the common looking drum on 67-69 cars and the flared on 70 and up.
