Almost...it would be more like this...
1.) Get the quick release brackets from Mittzy
2.) Get passenger backrest
pad,
sissy bar and luggage rack from
@Ishrub .
Apparently US Triumph no longer have ability to supply as many US members have said.
3.) Get EZ brackets from a variety of online sources
either @Mittzy 's Stainless or US sourced mild steel
4.) Buy the bags that you like. Like
@Steel I run Viking bags, but there are others out there
5.) Mount it all up
