Hi Colin,
Replacing the connector sounds like the right thing to do - not sure I agree that using a NOS part is risky, there's a quadzillion backplane connectors out there that have /not/ cracked with age after all, but I order from Digikey regularly and could order up a new one if you want.
I'm more than happy to lend a hand. How practical that is for you I'm not sure -'London' covers a big area!
If you are north(ish) of London then I'm just outside Cambridge and should have enough stuff around to do that and fix any issues that may arise, I've re-capped a couple of my TM500 series chassis and while a little 'awkward' in parts there's nothing too tricky about taking them apart.
Either shipping it to me or a visit - with free, quite passable coffee - would work fine. Oh, no cost (other than return postage) of course!
Adrian

a) Unsolder the entire faulty connector and replace it with the new one - this looks like a formidable task, since there are a total of 56 pins to unsolder and re-solder and access isn't straightforward but it would be the most ideal option, I think. Unfortunately I don't have a de-soldering tool, only a solder-sucker and some poor de-soldering braid (I suppose I could buy a de-soldering tool).
