    so is anyone running a SM420 in there post 1973 rigs? if so i want to know what you are doing for clutch linkage. i have a SM420 that does not have the ball stud located on the bellhousing like a SM465 does. Also wondering if anyone has fab'ed up a hydro clutch on the SM420.

    Just get a bellhousing from a '60-62 Chevy truck. Factory hydraulic. Factory SM420. These old trucks used a shared brake/clutch master. I suppose you could simply use only the clutch portion.

    Exactly what I would say... except dont spend too much time looking in 60-62 GMC's since they came with the 305 V6 and did not offer V8's (different bolt pattern on the bell housing).
