I have a 78 f250 crew cab 4x4 automatic 400 cu. It's a fixer upper that I purchased with drivelines sitting in the bed of the truck. I have finished some engine work, exhaust work, body work, and one to drive train. I replaced all u joints, carrier bearing, and proceeded to install the drivelines. Well in short the rear driveline does not fit. So lengths will help me determine if it's wrong drivelines, or reinstall of carrier bearings was wrong. I need lengths of the three drivelines.
