Yes, they are 7 & 9 pin socket connectors, but I have found some that look better and should have full length contact with the PCB lugs:

The lugs on the Predicta board are actually .060" (1.5mm) wide, so these are a little big, but I'm going to keep looking for others that will be closer to the 1.5mm lug size.
BTW, you don't have to break apart the 7/9 pin sockets to retrieve the connectors.....just grasp the solder lug end close to the phenolic base with pliers and give a good, firm push....they pop right out.
