This one's expensive through Amazon, but I'm sure you could find it cheaper elsewhere. Maybe your public library?

I don't know if this idea helps. But when I went to college at a state school here in IL, the college library had a whole bunch of General Motors and FoMoCo wiring diagrams, factory manuals, Snap On tool instruction manuals, and various other bits of print from the '60s and '70s. When a local GM/FoMoCo dealer moved buildings, then donated all the old out of date literature to the college library.

I found a 1977 vacuum diagram for my LTD and a wiring diagram for a '74 Lincoln Mark series. I asked if I could buy it since the last check out date was 1985 (this being 2006), they said nope.

i tried to buy some books here and they told me the same thing the sad part is they wont sell em but they will thow them all away
