[Heath] Heathkit HW-5400 Power connector

[Peter Brickey]

Hi,
   The power connector on my HW-5400 (Large 4 pin Socket part #432-1178) has
come loose from the rear of the transceiver.  
I would like to replace the shell with new one.  However, I cannot find a
matching piece.  I thought that it might be a Molex 
product, but have had no luck in finding one.  I looked thru my Mouser
catalogue and could not find a match.  
Anybody have an idea?
