Dunno about 'inspirational', but having just had to redo the bushes on an AMC twin - bronze bushes, steel pin - after 40 years of entirely blameworthy neglect in my hands, I wouldn't worry too much.
The AMC type have felt seals just outboard of the bushes, and a long thin 'spoke' which holds 2 steel end caps on the open holes, one with a screw to remove for lubricating with an oil gun now and then. More a case of 'hardly ever' in my case, but it lasted from 1978 to 2019 before they started to graunch. And - better still - pin and both bushes cleaned up perfectly OK after seizing, with no play at all, and it has been working a treat this past few months again. I thought that having taken over 8 tonnes on the hydraulic press to get the pin out, things would be seriously fubarred - but not a bit of it.
No idea whether there's any not-too-complicated way of blanking off the ends with something on the A and using oil through a nipple somewhere handy, haven't looked to see on mine, but if it could be done . . .??
