I finally got to look at this trans today and clean up the input and bearing retainer. They both had rust on them, but came amazingly clean. I used my crud thug with a medium wire and finished with 400 sand paper. There is super light pitting, but nothing that will be an issue to just use as is. The inside is amazing as well. The outside appears to have long term use, but it must have been behind a stock L48 that just didn't get abused. Every part inside is original and in excellent condition. Just amazed that I was able to purchase this so reasonably.
I didn't have the camera in the shop, I'll get pics tomorrow...
