So I'm working on a board that will act as a pass-through for a m/f pair of connectors interjecting to trace off some of the contacts to connect to another device for monitoring the signals. We did something similar for another project and the following image shows what I'm trying to find. I've found the right side's contact is called "PC Tail contacts" but I've been through like 500 pages of catalogs trying to find the contact on the left. Does anyone know what this contact is called and maybe where I can order them?

The right pins are going to get soldered to the board in through-holes and then the other connector will mate with the rest sticking out creating the pass-through for the two connectors. Any help would be appreciated as I've spent way too much time googling this and digging through catalogs.
