1968 B Body AC evaporator core removal

[VegasCharger]

I'm in the process of tearing an A/C heater box from a 1968 B Body. My question is how do you remove the AC evaporator core from the metal box? I was able to figure out the heater core removal part of it but having troubles with this evaporator. I do not want to cause any damage by error by trial. I've searched the internet on "how to-s" most of my luck resulted in the heater box only applications or the ones I did find on the A/C heater boxes did not detail the A/C evaporator core removal. I know it must come out because they sell new ones. Anyone on here done this before? Pics?

Thanks VC

make sure you get ALL the little hex head screws out, the drain tube outer extensions have to come off, it will come out.

the core is attached to a tray that slides into the outer box.

Thanks CDR. 

Are the drain tube extensions a slip over connection? Do you yank them outward for removal?

Thanks

they pull straight off, they can get corroded & my need to spray them with penetrating lube. they are soft,work them slowly .

Thanks again CDR. I was able to successfully remove the A/C evaporator with your advice. The drain tube extensions were a bit challenging, but with patience they came off. I believe that there were a total of seven 1/4" hex head screws that secure the evaporator tray to the outer box.
