I made a mistake when I ordered the ofna/hobao gears... I wanted the Hyper 7 2 speed pinions, but ordered the Hyper 10 pinions - oops. However... the ofna 1st gear pinion fits the cen clutch bell as a 1st gear. The ofna 2nd gear pinion wont work on the cen bell tho, the thread is too large on the pinion - m14..?? Both are hard steel - unsure of grade tho.

They seem pretty hard to find - trust me to find em tho... but anyway, I got a 13/17 set and a 15/19 set, so, as I said, the 13 and 15 would both work as a 1st gear pinion on the cen bell.

I am trying to get the ofna/hobao bell to go with them, hopefully this will be the end of my pinion probs... yea right... if not then its looking like Gen pinions on an Associated bell, like u say mate. Tricky to find much Associated stuff here in the UK tho.
