Ok, I've put a 1966 250 in my suburban (52 GMC). I used the66 bellhousing. Replaced the pilot bushing, cut tip off of main shaft of tranny. I was able to hook up all of the stock clutch linkage. Everything seemed ok til I started engine and realized the clutch wasn't disengaging. I used the 66 throwout bearing, clutch and pressure plate. Any ideas as to what else I need to do?
