Front Calipers in the Rear of race car Options

[porsche4me]

Hello - looking for opinions --and info --- are all 70-76 rear rotors the same ???

are all trailing arms the same ??? - are all the rear calipers the same ??

- I have a 914 race car that has no brakes mounted - the body is a 76 --- front suspension is 71 and I bought new rotors for all 4 corners. I have 6 stock front calipers (new and old) + the 2 early ones on the car --

-- and 6 rear calipers (new and old all of them need rebuild) -

-- I have heard people put front calipers in the rear , but should I put early or late front calipers in the rear --- I have both ---- dont care about the e-brake ..... thanks for ideas -- I need to buy pads ASAP ---- going to do Porterfields --- but dont know which ones to buy for the rear ------

This great info for the under-informed like me----- I have done the street car thing for years , where all of the car is either early or late ---- but this race car thing in kicking my mental butt ----- Here is what I have --- the racing series will not allow me to run 911 brakes or any crazy after market stuff ----- I have 2 sets of early front that are in good condition -- I have 1 set of late fronts that are good ---- I have 3 sets of rears (early and late that are all in need of rebuild that I don't have time for)

The race car has an adjustable proportional valve next to the shifter ---- So my original question is ---- can I run front calipers on the front and the rear --- with same or different pads, with the proportional valve --- and if so, early or late in the rear ( I think this was answered -- Early! right?)

Thanks again - it take a couple of time for me to get the understanding I need to move forward with knowledge
