I am trying to determine what fair market value for the following is…

* Pair of used rear 911 M-calipers. Is there a price difference for the early (with knock-back) and later (no knock-back and cup pistons)?

* Pair of used parking brake backing plates and associated hardware from a 70-73 911. I believe the 70-73 is the proper year range so that the mounting holes match the 914 trailing arm.

Condition? I am looking for working, but ready for rebuild/refresh. Basically what you might find if pulled from a running but tired 911.

As you can guess, I am looking to do an M caliper and 911 e-brake conversion on the rear of my car. I already have sourced A-calipers for the front.

I have some m calipers I got from 914sixer awhile back. I also have some 84 alfa romeo milano 48mm aluminum calipers that will bolt up in place of the m's. They have some kind of a black coating on them from brembo. The later models will be in the best shape probably. Everything is the same the alfa dosen't have knock back, it does use the larger pads than the m. The pistons are cup style and I'm pretty sure when I talked to zimms they said the a caliper cups will probably fit and they have some ss cups for a calipers for 33.50 each. It's not cheap to buy the rebuild parts so you can't spend a lot on the used calipers especially if they need pistons. I bought the steel armed 911 backing plates and about 84 944 angle pull adjuster assemblies, shoes and hardware all from the same wrecking yard including a 944 emergency brake cable and handle to put in the center. I also bought new vented rotors. I think if you know a local porsche wrecking yard you might beat the prices I paid but there are are no local porsche yards in Crawford or Waco, TX. I wrote up what I got and where I got it on other threads somewhere. Maybe also on the club site.

Erik has got the nicest rebuilt calipers and it will take a lot of work and expensive parts to match what he has.
