As a Winston boy, I'm biased towards Oliver's Driveshafts. DW here runs it. Great work. Chase over at East Coast Gear Supply can hook you up, too. Rides in Conover can do it too, I think, and they're also supporters of the board. Basically, there's a lot of folks on NC4X4 that would be excellent choices for the job, just try to find the one closest and support your local guy.
