73 Heater box with AC removal

Not sure what pictures you want. I have one of the firewall, the a/c unit was disassembly on the table. I have trouble posting pictures on this site. So can not guarantee them. What exactly would you like to know? The under dash vent is pretty easy, just a couple of fasteners on each side. J hook, yes, brn ground wire , controls and vac lines. It was all pretty much straight forward except the a/c box. There are 2 nuts towards the center of the firewall, top, there was undercoating on it and just couldn't see what was holding the unit in. When it's out , you can take your own pictures and get the renewal kits from Detroit Muscle.
I suspect if you have air coming out of area not selected, vac line crossed? I expect to have many issues too, as I took this apart last February!
