[65 GMC]

I have located a 1998 GM NV4500 with the original bell housing. I plan to install it in a 64 c20 behind a first generation 350. I know that I can use the NV4500 bell housing if I run a hydraulic clutch. My question is will the 1998 throwout bearing work with the clutch and pressure plate from the 64 or is there something else I need to do as far as a clutch and pressure plate goes? I planned on getting Capt fabs hydraulic clutch linkage kit. Thanks Ron
