Try Winget spares 01204 854650. they're quite helpful. I have that type of coupling on my dumper but think they're obsolete. I think they also might be a tad on ££salty side if available.
So the Rubbers are trapped within the steel plates and the steel inserts are top hat or pull into a taper?
No idea on the Shore rating, I would say around standard Oring so 80/90 shore.
If the damping material was machined how would you bond it to the centre?
You wouldn't. If the centres are bonded then the bushes were moulded around them. You're stuck with either fixing them mechanically or moulding new ones. That's why I asked if the centres were top-hatted.
You can buy pourable PU for moulding. Now you know why the rubbers are cloth lined, to get them out of the mould.

That was my thoughts. They are bonded as they have for and aft forces as the drive line changes lenght, thought the splined end of the propshaft should take those movements.
I have watched a ut vid where someone was pouring their own. While it sounds a good idea, I dont fancy it failing in the middle of nowhere.
Nice idea, not sure how much a 2nd would cost just for the platesPour a second one as a spare!
I have a vague recollection of someone re-engineering a Hillman Imp half shaft flexy coupling for use on their Sunbeam
