I am looking for these again and the nearest thing I can find is ED5002-ND from Digikey. Apart from the fact that these are .33cents each >> Mouser sells the Vector wire wrap pins. 574-T68/C is 100 bifurcated posts for $10.71 or 574-T46-4-9/C straight posts for $10.45.

While not suitable for complex circuits, simple >circuits can be crafted by adding jumpers to the component side of the board. Another options to consider . . . Emacs! You could lay out a board like that shown above (actually, the layout is already done) and order them from Express PCB. Minimum order yields 18 boards in 3 days for about $69. This board would accept a solder-cup D-sub along one edge and mate to 9-pin de-sub of your choice. The board is supported at one end on the mating connector. The other end with a screw and spacer. Alternatively, one could downsize the d-sub connectors like I did here http://www.aeroelectric.com/articles/macservo/macservo.html . . . and finish off the installation with a simple, over-all cover of heat shrink where the relay assembly is simply tied to a wire bundle. In this instance, I think I'd solder the relay to the board as opposed to setting it in a socket. This process would yield a very compact relay assembly with robust construction, very low assembly time and stone simple (d-sub) interface to your radio.

Protection for always hot feeders not exceed 5A in breaker or 7A in fuse or be fitted with the functional equivalent of a pilot controlled disconnect as illustrated in . . .. http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/Z32K.pdf My recommendations are based on what I know I could get certified on an T/C aircraft. Just how far afield one chooses to go in the experimental aircraft world is up to the builder.
