All I know is that they made some improvemnents (I believe) in 86 for strength and durability, don't remember but I think a shaft or bearing size was increased. So if you are pre 86, i would consider the upgrade kit.

The complete rebuild kit is around $300 or you can purchase a completely rebuilt one for around 1,300. Can't help ya on the torque specs, sorry.
