I bought them on Ebay. The listing was called:

"4 Pin Molex Connector Kit, 22-26 AWG .100 Pins Arcade Pinball"

And the vendor was "yorktown_arcade_supply"

Also, is a specific crimper required to install those contacts on
wires, or can tabs be bent over with a needle nose and then solder
applied?

I don't really think this is necessary as the DR7 does not draw a huge amount of current. If you notice, the connector pins are arranged so the plug will work either way it was plugged in. Based on personal experience in a factory setting (don't ask :) ) I'm guessing that one or more DR7s inadvertently got smoked in the Drake lab so someone decided to make the connection goof-proof in the field.

DR7 (the connector has 4 positions, but only 2 pins are used). As I am
putting together an order for maintenance parts while working on a project
radio, I'd like to get some of those female contacts, and perhaps a spare
connector housing. Does anyone know the manufacturer and p/n of those? I
have looked in the Service Manual, but haven't been able to find where they
are listed.

I have been able to order the Molex connectors from Mouser for the plug-ins
between the circuit boards; this request is just for the brown connectors
that plug in on the top of the DR7 board (including for front panel
switches and power transistors).

Thanks!
