Re: Repairing plated through holes.
Search Ebay for Copper Via Rivets. They are available in several diameters and lengths. You'll have to come up with your own method and tooling to stake them to the PCB, but shouldn't be difficult.

Hey - don't beat yourself up Dennis. The head might not be bust, there might still just be a duff connection. You didn't do something really stupid, like me when I plugged a harmonica connector one

Re: Repairing plated through holes.
Actually, IPC-7711 does allow a repair of a two sided board or a multi-layer board with no internal layer connections at the hole with a C or Z shaped wire as I have done. If you can get a copy, look

Re: Repairing plated through holes.
Do a search for "eyelet plated through hole" and you will find eyelets designed for that purpose. I do not know what kind of tooling they may or may not require. I have also used just a piece of wire
