I wanted to use "junk boxes on the ARINC racks myself and you can score 
them on ebay most of the time... but those dam ARINC connectors are not 
cheep.. some of my round Bendix connectors for my radios are 40 bucks or 
more. But that ARINC 600 connector is 500 - 800 bucks just for the dam 
connector with out the pins  and they are sub 5 bucks each..
So I hope you have DEEP POCKETS....
