I have a 914-6 transmission with the original OE 901 limited slip and the output flanges. It is disassembled. Transmission is stamped with# 5091383 on the bottom of the case. If there are more numbers you would like just ask. I didn't get the part number before I left the house. I am asking for $3,500. You can PM me or text me at 412-874-5846 with any questions.
Thanks
