I'll start by thanking some people who have helped already.
Gingernuts/Badger - for remembering that I wanted the frame and giving me first refusal, selling me the frame at a good price and letting me come round even though he was really ill. Awesome!
FluffyChicken - Gripshift advice
Rio - Black Rock-ring
Vinevo - 4 finger Shimano XT brake levers
I have also ordered some Gripshift, to replace the XT thumbies. Ha ha ha that alone will mean no BOTM for me. :-D ;-)
Got some Tange Superlight forks, which look identical to the ones in the catalogue pic above. The spec says Big Forks but they aren't in the catalogue pic.
Got wanted ads up for the rest. Need a DX headset too, and a new DX front mech, and some jockey wheels. And a seatpost. And a seat. And some suitable bear trap pedals.
