For a serious look at this exact phenomenon I'd highly recommend the Apollo AGC restoration done by Curious Marc and others for the 50th anniversary. They had to redesign and rebuild a few connectors down to the pins to actually restore things. There's also a lot of other crazy stuff they had to do, including putting some of the electrical modules in a milling machine and drilling them out to replace bad parts.

particularly parts 10-13 I believe are where the pins and contacts come into play.

Except Marc's team actually had highly detailed mechanical drawings of those parts, so the only hard part was finding someone who could manufacture them. Thankfully they had connections in that area.

Yea, that definitely made things immensely simpler but it's still a good reference for seeing what kind of problems happen. I'd also imagine that for most connectors you aren't going to need nearly as robust or detailed drawings or data about them to make something that will work. In this case they also wanted something that would mate up perfectly without any possibility of damage or excess wear on the connectors.

To be fair, it's possible to handcraft one or two connectors... might take some time, though.

200 years from now we'll just scan the originals (or bring back the digital archives) and 3D print them on our multi-material micrometer-resolution printers.
