I’ve read a bunch about it, but a little confused. How can I make them the same length, swap input shaft on the Tcase, put an adapter between them, both? I would love to leave Tcase in the factory position and not mess with driveshaft lengths. Thanks!

I have been there and done this on my thread and had 1.5" longer than what I had before . though i took out a sm465 /bathtub np205 and replaced it with nv4500/round pattern 205 with short input swap.
