Thanks to @angusmcoz I ordered the kit, removed the passenger pegs on my 2019 Tracer GT, put on the FJ09 brackets and now have lots of room for my feet on the pegs.
I don't have passenger pegs and don't need them.
This is documented here: https://advrider.com/f/threads/yamaha-tracer-900gt.1266110/page-57

BTW the kit 2PP-F84G0-V0-00 includes everything you need to install the brackets including the rubber caps
