So, I’m replacing the clutch in my 1951 3100 that has a 1954 235. I pulled the clutch, pressure plate, and flywheel ( all need help). Pulled the pilot bushing out. It was tweaked so instead of a cylinder with a straight hole in the center, it was more of a parallelogram with an angered hole. Input shaft and end of crank weren’t damaged. ( was wondering where the vibration was when I drove it; rebuilt the whole rear end, had a new balanced driveshaft made, and still had vibration!). Got a clutch kit with all needed parts. My question is: Does the crank end have a bearing in addition to the brass/bronze pilot bushing? I notice a larger recessed circle around the pilot bushing hole. Also, noticed it has a 9 1/2”clutch , so does that mean the 54 engine came from a car? So many questions.
