Armstrong air conditioner needs

[Lcrupper]

I’ve got a 1965 Caravel that has the original Armstrong A/C. I found a servicer with experience and appears it is workable. Is charged and fan is very free ( like new). I need the relay for the unit. Can’t find any information at all. Have original parts number but nobody has a clue how to cross reference for a part. I NEED HELP ! I am on the track of one in a salvage yard but am only mildly optimistic. If anyone has any information please let me know. I can’t find any repair manuals. There should be an archive somewhere but I sure can’t find it. Thanks for any input.
