Factory A/C question

[chevyrestoguy]

I'm starting to assemble the missing parts from my A/C set-up on my '64. Everything behind the dash is missing, including the heater box on the engine side of the firewall. I have bought 2 non-A/C heater boxes for parts, and hope to find an A/C specific one in the future.

My question is: Could the standard OR deluxe heater be ordered with the A/C, or did that option automatically require the deluxe version? My '64 has dealer-installed factory A/C, and I'm just trying to piece the puzzle back together. My heater controls appear to be standard. The truck is at a buddy's house, so I can't investigate until this coming weekend. In the meantime, here's a picture of the dash, taken when I first bought the truck:


Any help, pictures, or reference material would be greatly appreciated. I have a line on an incomplete A/C set-up, but I want to do my homework first before I commit to buy it.
