sorry for the long post,

Ok starting out, replaced my transmission about a month ago. Before changing it out, I had a borg warner st-10 w/ 11" clutch 26spline... no problems until i chunked 1st gear... haha but anyhow thats not the problem. Replaced that transmission w/ an M21, again 11" clutch but replaced the whole clutch setup. Ran it for about a week and really had no problems. Eventually I noticed the pedal sort of sticking when i let the cluth out and it would jerk out suddenly. I traced the problem to the groove inside of the throwout brearing. Apparently the nose cone on this transmission was a tad bit shorter or something b/c once most of the grease worked out of the throwout bearing the groove began to clip the tip of the nosecone on the way back in. So i replaced the t/o bearing with one that had a slightly different grove on the inside, greased her up good and it worked great for a few weeks. Now im noticing the pedal getting sort of stiff again like it might start the same problem, so im kinda stuck and tired of taking it apart and putting it all back together.
