GM 3 speed manual trans It's not a T10. It's maybe a mid 70's 3 speed. It was in the backseat of a recent parts car purchase. I don't know the condition but the casing has surface rust on it. But anyway local pick up only. Not shipping this beast. Shoot me your e-mail adress if your interested after repling in the thread and I will try to get some pics this weekend if not sooner. Starting to get dark out here already! Sold as is $ 150. I'm in 60586 Thanks, Brian
