Evaporator/heater case

[BubbaMope]

I'm looking to replace the evaporator/heater case on my 1970 factory air car since finding the vacuum control cannisters seems to be impossible. Vintage Air sells an E-Body evaporator/heater kit. Anybody know if I could use this in a B-body without extensive hacking? My car does not have the correct air in the tires and function comes before anything else for me.

E body will not work. I got mine from a 66 Fury. Better quality I guess. Same AC unit too,with a few minor diffs.
