Mittzy's listing is just for the custom quick release side brackets and extended length 8M and 10M bolts to suit.
You will also need a Triumph factory accessory rack and sissy bar with pad to suit.
I am not sure if [USER=3630]@Mittzy[/USER] has any racks and sissy bars left.

If he cannot help I have a couple of spare used factory chrome ones in the shed and one that was painted black but needs a respray.
The other trap for unwary buyers of new old stock Triumph sissy bar kits is that they DO NOT come with the sold seperately passenger backpads which sold out year ago.
See here. Not mine these are from a UK Triumph Dealer
GBP 395.00
Approximately US $475.64
