Aye Steve,
This is the contact that you require for the fitting instructions and maybe fittings for the fairing:
Powerbronze_Fairings_linkI cannot remember the specific name of the Powerbronze fairing model that I had!

Could be 'Daytona' or 'Endurance', depending upon the headlights you have, mine I believe was an 'Endurance', with the twin headlights.
Smudge had the Powerbronze and fittings that was fitted to an SRX twin shock that I acquired and he then fitted it to his XBR/Welsh sidecar combo that he rode home from Wales, some years ago. You'd need to use the 'Search' box in the top right of the screen to find the 'thread' on this forum. I believe that there was a fair bit of jiggery pokery, due to the conversion from SRX to XBR and the sidecar on the side.
All the best, Bill
