Here is a close up of the stamp. Not sure how to explain this one other than this is how I got it. Sound like an M22 and shifts like one that's for sure.
Here is the countershaft. Again, it had a small drip early on. On a recommendation I used JB Weld to band aid it. I don't believe it leaked since and that was in 06. Or at least there is no fluid on my garage floor.
