65 Rear End Question

[Realmongo]

There is so much conflicting info that I decided to take the backing plate off and look for a part number. Here is a pic of the backing plate. There is a FoMoCo stamped into it on one side and KH 70866 across from it, the KH I'm assuming is Kelsey Hayes.

I searched that KH number and found a Cougar site that had a couple. They state that they were for 1 3/4" brakes which I'm thinking is good news as I could just order the rebuild kit that comes with new drums for the 1 3/4" shoes. I can't seem to confirm anywhere that that's the backing plate for the rear on a 65 V8 Mustang though. Does anyone have a wheel & drum off at the moment (or one laying around) they can compare to.

In the pic you will see a red arrow pointing to the stamping on the backing plate. I think the depth of this stamping might be deeper than what is on a standard V8 car. Anyone know?

I just went out to the shop and looked at one of the sets I have on the shelf and they are stamped KH (yes, KH is Kelsey Hayes) 70866 and 70867, so it sounds like you still have the original backing plates.

Ok I think I may have this figured out. The drums are marked 1125B which research tell me are front brake drums, not rears. I think what happened is someone has, in the past, mounted front brake backing plates/drums to the rear axle. Since the backing plates are for 10" drums and the drums are for 2 1/2" shoes I think (hope) that I should be able to go to a junkyard and pick up a set of drums from a 1980-89 LTD or Lincoln Town car and use those.

At least that's what I'm hoping. I read it on the internet so it must be true.

If the backing plates have the divots and holes for e-brake cables, they are not front plates. Not to mention, it appears that Realmongo has already ID'd the plates (at least one of them) for you.

Sorry RealMongo, I missed that one somehow. Thank you a TON for checking that for me. Thanks to all others who tried to help here too, you guys are awesome! Now that I know I have the original backing plates I can proceed with the standard rebuild kit.

Cheers to all.
