Re: 1974 C10 A/C Hardline Routing

I should have taken a picture of the hardlines before I scrapped it. Does someone happen to have pictures of the condenser and the a/c lines in the core support area? Or if someone could explain where they run to that would be great.

On my truck there is a line that runs from the bottom of the evaporator and goes through the passanger side core support, makes a 90 bend and then stops. On the drivers side the stock rubber hose from the compressor terminates at the core support. My new condenser has #6 and #8 fittings on the drivers side. I found a hose shop in my town that can make new hoses/lines, but I would like to give them a general Idea of what is going on. And I would like to know myself. Any input, and or pictures are really appriciated.

Thank you!
I can't help too much on a 74 as the later 70's ran both out the drivers side for the condenser hookup. Im surprised you found a parallel condenser that was setup that way. i couldn't find one when I was looking.

Checkout my build and scroll to post 66 it pay help you a little for the small lines at the core support.
