clutch, input shaft, ipt. shaft bearing, rear motor mounts, rear main seal, had the flywheel turned, replaced the mid-shaft bearing, and all the u-joints.

(Just some FYI)...
Those rear housings / flywheel housing gaskets usually last about 800k+ or more miles (sometimes a million+) if the engine and truck is driven right ... however they tend to leak more often than normal if someone is hard on the truck, it is programmed with a lot of torque (1850+) and/or if someone is often dumping the clutch, lugging the engine, etc. -- You see one leaky on a truck that only has 500k miles or less, it is almost guaranteed that someone has been abusing it and/or driving the piss out of it / has bad driving habits.
