Yet another caliper question

Having trouble getting the right rebuild kit. First thought the calipers were the fronts off the 70' 914-6 which had been moved to the rear. Then thought they were 84-89.

Here is what they measure.
ATe calipers
42mm pistons
13.88mm spacer
3in bolt pattern
single bleed valve
The piston boots are the type that use the metal ring to hold them on.

From what I could find the 84-89 should have 11mm and the Sc should have 7mm spacer.

I'm not sure but they do sound like Carrera rear calipers. Up through the SC the pistons were 38mm with 10mm spacers. The Carrera went to 42mm pistons and the rotors went from 20 to 24mm, so the spacers should have gone from 10 to 14mm.

Fronts on the 914/6 were 48mm. Fronts on the early 914/4 were 42mm, single bleed valve and very similar to the 911 rear. I suppose they could be an early 914/4 front with wide spacers installed, but then the brake line goes in the back and not the bottom.
