I have a 1989 blazer just put in a dana 60/14 bolt. I've ran this combo before on another rig and didn't have to change the drivelines just lengthened the rear. But for some reason this time the rear driveline is not fitting in the 14 bolt yoke because of the u-joint c clips. Also before I get too far into this problem i'm going to put in a turbo 400/205 soon will I need different drivelines at this time? or will these half ton stockers work?
