Amp Mate-n-Lock connectors found their way onto the single engine Cessnas in the 60's. I can't speak to the WeatherPack connectors specifically, I've not had occasion to work with them. But it seems that any tool that extracts male pins would work with the female sockets. The White Products catalog page 24 shows only one part number for an extraction tool. Emacs! So I'm assuming that the T-3 tool is designed to extract both types of pin. I'm skeptical of the 0.020" measurement you cited . . . those pins are much larger . . . did you 'zero' the caliper before making the measurement? Measurements aside, the single tool should work with both pins and sockets. You may have the wrong tool.

Excellent . . . details, details . . . always those pesky details. Fly comfortably!
