Does it matter what I get the non transmission parts from, ie. I would like to pull the clutch pedal assembly and everything else from my 96 car that had a WC t5, but would all that stuff still work if I wound up putting say, a t56 into the car?

 

I believe the 4th gen pedals are all the same - I pulled the wire connectors from a 2000 Pontiac Sunfire GT (I believe) and they looked same as mine from a 4th gen Camaro/Firebird. I would compare yours to an actual set from a T56 before proceeding, unless anyone else here can confirm.
