This year didn't come with a super t10. I suspect the driveshaft I'm using is giving me a driveline vibration. Perhaps it isn't balanced correctly. I want to get a new yoke for my original 350 auto trans driveshaft and try it to see if it solves the issue. Super t10 is from a 76 firebird. Do I order a yoke for a firebird? The rear end in it now is out of an 81 camaro. Are the u joints larger than the 76 rear end?
