So, I am at the end of a build of a 1971 VW Camper van with a 3.2 911 engine (PMO carbs etc etc

We have built front and rear ends to use Boxster brakes and all fits and works but now I want to rebuild the calipers.

A few years ago when I was collecting parts I bought a set of Boxster S brakes which were too big to fit inside the wheels so then bought what I thought were Boxster (non-S) calipers that fit.

I am trying to figure what model of calipers they are so I can order rebuild kits. The part numbers on the calipers do not seem to be porsche part numbers (maybe Brembo?). When I search for part numbers they dont quite line up?

What I do know is the following:

Piston sizes:
Fronts
39.9
35.9
Rears
29.9
27.8

And here are some pics. Can anyone identify them and if possible, let me know good places to get rebuild parts?
