I have also been looking to get better gearing and was considering a rear end or tranny swap. I have read quite a bit about this t-5 swap but most are on the 50s models. Is this swap do-able on a 66 c-10. I have the Muncie Hd 4-spd and a 4.11 rear Iwould like to make more hwy freindly. I have been to most of the links and threads, great stuff but haven't seen much w/c10s. Regards, Dennis
