[Milsurplus] Dynamotor mounting

[Jim Isbell]

I am looking for the "pegs" that small radios and dynamotors are mounted 
on in aircraft.  I am talking about the pointed pins that mount to the 
bottom plate so that small chassis can be placed over the "pegs" and 
then a slide lock latches them to the mounting.  Dont have the slightest 
idea what you call them or how you measure them.

Any suggestions??
