This came off my '91 110. Functional when removed. Drive shaft u-joints may need a little rework. I was hoping to put it back in, but the BT6/NV4500 combo is too long and I'm up against the rear cross member. I opened it up, cleaned, greased, and resealed it. All looks great.
Complete with output shaft, and engager rod (a simple hole and bushing in the passenger side battery box front wall is all that's needed).
It bolts in place of the rear cover plate on the LT230. You do need to check if you have the star on the back side of your transfer case input gear (by removing same rear cover plate.
