B5 A4/S4 calipers on B4?

[YourPalBigAL]

Does anyone know if the rear calipers off of a b5 will swap directly into a b4? Just bought a 1995 Audi 90 last night and the rear brakes are so effed. Calipers and rotors are junk. Figured it's a lot easier to source b5 parts than it is b4, so if the calipers will fit I will just buy some b5 calipers from the junk yard.

I used a B6 calipers, new are cheap and available anywhere, you have to re-route the flex line, not a big deal.

S4 caliper will require you to get creative with rotor choices.
Best to go straight for 5 bolt and swap the B5 A4 hubs at the same time... ;)
