OK it is in fact the 5 speed in an SR5 1980 2WD pickup. The truck was in a rollover years ago so I would assume the trans was working when it was wrecked.
I am located in Highwood MT. I would be willing to send it to you for $25 plus freight. I figure the $25 should cover packaging materials and you can just have the trans. If you are interested let me know via PM and I will try to get a shipping quote. Might be too much, I don't know.
