Sunday I installed the new rear driveshaft from Denny's. Nice, quality part. Had to source a new yoke for the rear of the transfer case as a CV joint does not bolt up to a non-cv yoke. Not much info about the Dana 21 transfer case out there. I can tell you that a yoke for a Dana 18 / 20 with ten splines fits perfectly. Neapco p/n 2-4-4061x for a 1310 series cv joint.
