Bottom line, bugger! I can get part no. 30205, which is 25mmIDx52mmODx16.25mm tall, but that means reaming out the headstock to suit, or you could use the XL250 brng set, but that means shimming up the headstock with 0.75mm thick tube, so haven't been able to help, sorry man.
At least you know what your up against now I spose!
Did something similar years ago, and reaming out the headstock, then fitting a machined-up inner pipe to restore strength was how I went, but I'm sure you know what you doing man.
Thanks for the research.
I will have to pull the front ends off both bikes and see what I have to play with once a rule has been used.
I may have to machine up bearing carriers for both bearings and weld them in place in the steering head.
