Kyosho driveshaft help

[KRob]

I've got a Kyosho Triumph in pretty good nick that will be a runner at some point (albeit rather slowly).
Only really needs the rear driveshafts sorting. It has some yellow/gold alloy ones in there at the moment. Wondered if anyone knew who'd made them?

Because of the adjustable width hubs on the Triumph they do fit but need to be on the wider setting, this makes the car too wide so I'll be replacing them with standard Kyosho items.
I know the original dogbones and axles are OT-6 and OT-18, but am I right in thinking the UJ replacements would be W5063?
Any help appreciated.
