It's hard to tell by looking at the pics if your clutch plates are good or not, but since you're neck deep into your project now, I'd replace them. As for your POG, you'll have to do a little more engine work and split the cases to get it out. You're almost to that point anyway, so it's not a big deal. To fix your 2nd gear issue you'll have to get in there anyway. I just went with an OEM steel gear. I don't think it cost more then $15. The gasket kit was the killer. I like the debris field in your garage. Looks like you were on a mission.
