Hello Jeff,
I’m not sure if it can be done using the original wheels, there may be clearance issues, if I remember correctly.
I did one soon after they came out using Alan Gibson wheels, and it formed the basis for an article with plenty of pictures in the very first issue of Finescale Railway Modelling Review in summer 2014 (Bob Barlow’s magazine of which there were only 3 issues), if you can find one.
Good luck with it…..disassembly is not easy as much of the chassis is glued rather than screwed together!
