this is what i have done to several 904s

removed the 4 clutch/steels...

installed the 5 clutch/steels..using the thin ones..i get about 50-55 thousands clearance which i think is too tight... I take the pressure plate that is in the clutch pac to machine shop..have about .020 removed to get .070-.075 clearance..

so i am using stock clutch/drum..and stock pump.
