67 A/C heater box rebuild and install help

Steve,
I have another box from my car original owner decided to "add" a/c to it although it didn't come with it. all factory pieces and unfortunately the not so unsightly holes in my firewall.
if you need some pieces let me know I have almost the whole assy from compressor to vents.

also, seal off and cap all lines as you clean them out to avoid any further contamination. before charging - putting a good vacuum on that thing before charging is imperative. no less than 30in vac to boil out any moisture and I would hold that constant vac for several hours.
