Rear brake pads for /6 - same as /4? Options

[smontanaro]

I need some rear pads for my /6. Are they the same as the /4? I was having a little trouble figuring that out on AA and Pelican sites, though I suspect they are the same.

Thx,

Almost all pads need to have the holes drilled out by now. Most companies don't make 914 4 or 6 rear pads anymore (with the larger holes on one side)

914-6 rear pads are the same as the following pads:

Early 914-4 Fronts
Early 911 Fronts (with M-Calipers through 76)
Early 911 Rears (with rear M-Calipers through 83)

These pads are as common as the calipers they came in so they should be a dime a dozen. Most european sedans had M-Calipers on them at one time or another so they should be easy to find.

914-4 and 914-6 rear calipers are very different. While most wouldn't notice this in a picture you can tell by a few visual clues and the following:

* Pistons - 33mm for the 914-4 caliper and 38mm for the 914-6 (same as most 911 rear pistons)
* Pads - Smaller AP30 pad for the 914-4 (same as very early 911's and 912's) and AP31 for the 914-6 (again, same as most 911's through 1983)
* Larger overall bodies. The nose section of a 914-6 caliper is the same as the 911 rear M-Caliper.
* No casting ridge on the inner caliper 1/2 spine. 914-6 calipers have a smooth spine on the back 1/2 of the caliper. 914-4 calipers have a raised ridge along the spine of the inner 1/2.

I realize that's probably TMI but theres probably a lot of people that would like to know the differences between the two calipers.
