[OM] need a part number for relay cord

[Johnsonpa]

My relay cord is missing a piece on the end that attaches to the motor drive. 
 It is one of the two spring loaded pieces that effectively keeps the relay 
cord attached to the motor drive.  Anybody have a schematic with part numbers?

I'm also looking for part numbers for:
The little springs that make the contacts on the MD1 or MD2 protrude from the 
bottom (I couldn't discern them on the Oly Hardware Resource Page - a 
fantastic site!)
T-28 Twin flash tubes
T-32 battery cap

TIA,
