This part is in excellent used condition and is dated GM part, dated May 1969.  Very hard to find with good threads and not damaged 50+ year old factory part. Had new rear bushing and seal installed once before and was removed from a fully rebuilt operable 1969 Chevy transmission, removed in 2024.

This is the type that takes the smaller rear seal, bushing for the real oiling option GM used specific to this part  number GM # 8623214

EXCELLENT USABLE CONDITION--CAN GLASS BEAD AND CLEAN FOR $50.00 ADDITIONAL OPTIONAL FEE, BUT READY TO INSTALL AS IS.
