Thanks for the drawing. I'm not re-installing the Mopar underdash A/C unit. The hoses were cut off in the engine compartment. They cut the dash frame to install it back in the 70s. They routed flexible hoses to the dash vents they had cut in the dash frame and stuffed it all up under the dash. They had to cut the glove box down to 1/3 of it's original depth. Going back stock for now but may install a Classic Air or other brand under dash unit soon. The holes are already in the cowl for the hoses. There's the option to use the unused wiring for it. Since the dash frame is out, now is the time to decide on the a/c seems like. The original plan was to use the Charger for nice weather long trips, so a/c would be needed. Now that we have a 2015 Shaker Challenger, it's hard to beat the modern conveniences for travel. We've used it on several trips over 1500 miles and it's nice.
Again, thanks.
Terry
