I'll ask brian in the morning, they may even have a spare yb crank, you could always have your old one built up size wise, easy to do with the right kit.
Brians been doing machining/engine building for 54 years so is bound to know, does mostly just competition stuff, it's who I use and trust 100%, pm me if I forget to ask, or phone him on 01359 251888, ask for brian or barry.
I put my crank in today, after cleaning everything etc etc, used the OLD 200,000 mile thrusts and have 5 1/2 thou thrust clearance, which is pretty astounding as up to 8 is ok on a NEW set, crank turning torque is under 2lb ft!!
