I was going through my clutch linkage on my '63 C10 today. While wiping the grease off, I found a (plastic?) O-ring, for lack of a better term, around the ball on the engine-to-bellcrank stud. It was badly deteriorated, and I dug what was left of it out, unfortunately before I thought to take a picture. You can see the groove in the stud where it was. I went to look for a replacement o-ring online, but I could only find a whole new ball stud, and it was a little different from mine - It did not have an o-ring at all. Another difference was that my stud is pressed in, with the end splayed out to make it a pretty permanent installation. The replacement I found online was threaded, and the description said it threaded into the engine block. Mine is attached to a bracket (visible in the pictures) which is in turn bolted to the block. I wonder if this is because I have a later model 250? Does anyone know were I could get a replacement for the o-ring? If not it probably wouldn't be all that difficult to remove my stud, thread the hole, and put in the replacement, assuming it is the same length and diameter. Any thoughts, comments, or experiences with similar problems would be appreciated.
