Need help choosing a junkyard engine

Wow, I can't stop thinking about it. 6 years ago I was stationed there while I was in the Marines. I drove a 75 duster w/ a s6 that ran great. Long story short, my EX wife screwed me over pretty good and I was forced to leave it there when I got out. If you see a gold 75 duster w/ black and grey interior try to get it. lol
