just a tip.....if you want a king cobra to last more than a few thousand miles, break it in properly. im only saying this because it seems like you arent doing it. as far as the throwout bearing goes, you own a mustang. it is natural for the throwout bearing to make noise. if it is squealing loudly, it was not lubricated properly when it was installed. if it is just a somewhat quiet chirp, adjusting the cable may remedy the problem. i just did a king cobra, fidanza flywheel, aluminum driveshaft, steel bearing retainer, and tranny mount and no vibrations, squealing, or anything else abnormal. as far as your vibration goes, it sounds like the driveshaft was not marked before removal and whoever did the install, put it in wrong.
