Ok guys, I may be crazy but I really like my 203 xcase. I just got an 81 3/4ton 4x4 pickup with a 208. My 79 Blazer has the 203 and I would really like to swap out the xcases along with the engines and tranny. The Blazer drivetrain is built and the trucks is most definitely NOT built. Can somebody tell me whats involved besides new driveshafts, I've swapped engines and trannys but never a xcase. HELP!
