I am looking for a diagram of the vaccum lines in the dash of my 1970 442. Does anyone have a source for this? I have an a/c car with heat.
Thanks, Gary

 

SOURCE: 1972 Product Information Manual (PIM) some refer to as Factory Assembly Manual (FASM). I suspect there may exist some diagrams in the CSM, as well.

 

The factory Chassis Service Manual has this diagram in Section 1, page 1C-13, figure 1-23. If you don't have a CSM, get one. It's the best investment you'll make for your car. Get a paper original, not a reprint or PDF. The latter all have quality issues. There are currently over a dozen original paper copies on ebay.
