OK, I should get some pictures of this, as the next step is also working nicely. I was able to drill a hole in the plug at the correct location. Separately, I found some brass tube on the junk shelf that is a good fit to the contact in the socket. I drilled out the hole in the plug, making it an interference fit to the tube, and also rolled over the end of the tube to form a radius so that it plugs in smoothly. This plugs neatly into the radio, and will enable connection to the audio section without modification of the chassis.

Cheers
