Ok, flame away. I picked up a 88 F250 4wd, as a work truck. The T case is a BW 1356. Anybody have experience with this unit? Good, bad, things to watch for. The rest of the drive train is 460 FI, ZF 5 speed, Sterling rear, and that weird Ford front axle with exposed shaft on the pass side with a high pinion. FYI, I looked for a Chebby, but none closer than a 4-5 hour drive. My thanks too all who contribute to my fund of knowledge.
