What would you pay for this 79 Ranger Lariat? (parts truck)

[Kellxr7]

Found another donor truck for my slick, a 79 Ranger Lariat supercab longbox, the guy that is selling it doesnt know a whole lot about vehicles by the sound of it, he 'thinks' has a 351. (which doesnt really matter to me because I am mainly buying it for the front discs etc.) & will end up parting out what I dont need. Said it ran when it was parked 4 years ago, basically everything is there except for lights. He said to make him an offer...

i would offer hime scrap metal price plus a little extra
50 dollar bills look pretty good right now in this economy , so have the cash ready
tell him he is getting more than the junkyard will give him.... and he doesnt have to do a thing
start low..... you can always go up
