Keep Your Cool! Vintage Air Sure Fit Install in a 67 C-10

[67ChevyRedneck]

The next part is up for debate on how to do this. I wish I would have installed the hoses/lines with the unit loose in the cab so I could tighten everything easier with the firewall cover OFF, but lessons learned. It wasn't that hard to do, just a bit of a pain with the firewall cover on and the unit bolted snugly into the cab. In hindsight I would have left the firewall cover OFF until last.

Remove all grommets from the firewall cover so it's easier to push the hoses and lines though. I started with the #6 hardline that goes from the underdash unit to the evaporator. I put the grommet on it and put it through the firewall cover.

Don't snug up any of the grommets until all the lines are installed, it's much easier that way, but also, DON'T FORGET TO PUT THE GROMMETS ON, you don't want to have to unhook lines and buy new rubber O ring gaskets.
