Bought a second hand flywheel and a brand new clutch kit to put in my PU When I bolt the flywheel up and then put the clutch disk up to the mating surface the clutch 'springs' catch the flywheel bolts. Viewed from the side the clutch springs are above the surface of the friction material. Took the washers off from the bolts and it still catch's (yes I know the washers are on in this picture, just wanted to show the relation between bolt and flywheel surface) I have the clutch disk around the correct way. Have an old clutch disk that has more clearance on the flywheel side, fits perfect but is the wrong spline. So, can anyone advise what clutch disk I actually need? Ever so slightly annoyed as I had a free afternoon (with clearance from management!) to get the engine in the PU. No telling when that might happen again! Ah yes, Engine is a Chevy 350, Clutch is an 11" and the input shaft is 26 spline. So.... What clutch disk do I need in order to fit the flywheel?? P.
