100 pieces... M39029/58-360 crimp socket contacts for HIGH DENSITY DSUB connectors. Primarily for use with AMP series 109, and other equivalent D shell subminature connectors, these contacts are used in many avionics installations, including Garmin 430/530/300XL, GMA340, GMA347, and others. For many Garmin installations, this is not the only contact you will need. Please see my other items for more contacts and contact kits.
These contacts are over $1.50 each from Garmin. Don't even think about doing that expensive installation using cheap Ratio Snack formed crimp contacts. Do it right, and use the Mil Spec machined crimp contacts.
