Cheers. I enquired locally with the dealer ( 1 hr away ) they seemed to think there wasnt a Triumph one. I e-mailed Thunderbikes here in N.Z. 2 months ago and im still waiting for a positive reply other than we have refered your enquiry.... I just thought I could ask on this forum and somebody would know. I might have to pull it off and take it down and match the shaft and the thickness and select a 19 toofer I guess. Thanks anyway.
