Help me ID my 18 Spline Tranny...

Ok, you see the input shaft gear. in the front? that has been machined and had a collar welded to it. It is worn out, and not something that can accept a syncro. That means, really, that box is raced and used up. In my OPINION, all you have good, is the cases halves, and maybe a good cluster gear set. its worth whatever those parts are worth.
