right yesterday ordered a 944 m/c and it arrived this morning
. Went to collect it (genuine ATE £97 UK pounds)
..thought it would be tricky to fit with front/rear outlets being vice versa, but the front pipes reached the rear outlets no probs, and the rear, well when i fitted a 'T' for the switch and made a stubby pipe to go to m/c all fitted well !
the other possible stumbling block was goung to be the reservoir pipes into the m/c. the 944, as bug ones as large dia. fittings that go in. my Audi m/c as for the type 3 one has smaller ones - the type 3 has one of these fittings real flat so the tie rod can pass over it, but these ones were too small for the 944. i had a new set of proper bug ones, fitted them and re-routed one of the res pipes over the tie rod - thought i'd be tight on space with gas tank but plenty of room! so another problem sorted !
the piston rod on the pedal which i had previously extended for the audi m/c (by 15mm) was perfect for the 944.
pressure bled the brakes again..
lo and BEHOLD-
I GOT PEDAL !!!!!!!! 
All I can say is many thanks, especially to Lanner for the 'logic' and thanks for the power of the internet and sharing of information
pics below. just to prove a 944 m/c CAN be fitted to a type 3.
Cheers guys, Angelo
LONG LIVE THE GERMAN LOOK - THE HOME OF INNOVATION !
