Default M21 trans question

I noticed that my shifter linkage was feeling a little sloppy the last time I drove the TA, so figured I’d take a look underneath. I had also noticed that I was leaking a little bit of gear oil. Here are some shots of what I found, as well as a couple of questions:
1. Does this leak look like it’s coming from the tail shaft or more like where the tail shaft and body connect? Or both?

2. Like the engine, this trans was rebuilt less than 5000 miles ago, but probably close to 10 years. How easy is it to replace these gaskets with trans in car?

3. If I have to remove the trans (I’m pulling the engine next month anyway to build a 4.00” stroker), what do you think of putting M22 gears into it? I love that rock crusher whine.

4. How can I determine if this is the original trans. I believe it is, but just to double check. Is there a VIN stamped on the case? I took a photo of what looked like that.
