What's the rare part you need for the Lincoln? I have a 79 MkV out back that I might part out. It ran great when I Parked it in 94 because it needed tires and was only getting 10 mpg. It's a Florida car so the bottom edges aren't rusty like most Maine cars but it rusted through over the windshield and through the hood since it's been sitting so I'll probably never use it again. I'll save the white leather interior and the aluminum wheels will go on the Ranchero. The rest is available. It's hard to sell Lincoln parts on ebay.
