Armstrong A/C Start relay replacement part

I am finally trying to repair the old Armstrong TRH 25-14 unit on my 1976 Overlander. (This is a hot year). The part I am having a problem replacing is the Start Relay. I can not find a direct replacement for the one I fear is my ultimate issue. The existing part indicates it is an Essex RBM H-18-E 128306-1955S. It has a total of 4 wires in on a total of 5 terminals. Does anyone know of a Grainger part number for a new replacement or part number for another source that I can acquire that will fit in the space? I have scoured the forums and found all the Capacitors to replace but the relay has me stumped. I appreciate any help I can get.
