Anyone have a diagram or information on vacuum lines for vent door operation. I had to change the heater core on a 76 that I am restoring. I removed the back compartment under the dash that contained the heater core and attached are vacuum lines. I have two lines damaged to the point that I can't determine where to run the new line to.

 

Maybe purchase a Chilton's manual?
Just a suggestion for future reference at hand.

 

thanks, I already have both manuals and I don't see anything in the books about the subject. Will check again.

 

Here's a site with a gazillion pictures/diagrams
