I’m replacing the clutch in my 1962 k-20 with the 235 engine, sm420 transmission with the hydraulic clutch with the passenger side slave cylinder. 10 inch diaphragm clutch. Truck is pretty much all original. There are two holes on the clutch fork. The shop manual says the outer hole is to be used with the 235, the inner is for the 261 and 283. Mine was set up using the inner hole when I got it. If I try to use the outer hole, there is too much angle from the slave cylinder. The inner hole is pretty much a straight shot. I’m concerned that using the inner, there will be too much throw in the fork, which would wear out the pressure plate. Should there be a spacer behind the slave cylinder on a 235? Moving away from the block would make it a straight shot to the outer hole. Does anyone have a picture if so? Any thoughts? Thanks in advance for your help.
