Jaymanek, I agree re. cost of ZF v. Getrag. I installed my Getrag for less than $1000.oo, and couldn't be more pleased. However, I agree with Dan regarding originality, although my car was not bought with its' future value in mind. I have kept all the original parts, incl. 4 speed, drive shaft, mount, shift linkage etc, so the car can go back to "as it left the factory" condition , should a future owner wish.
