I finally found them in my shed in the first box or two I had removed before fishing through many many more.
To cap it off they are not as I described earlier but this 3 position
Premium Mini Boards 5-½" long x 4" wide version with the splined adapters for Triumph Rocket 3 front rider use. The ones on my bike are the chrome 5 position ones
8-½" long x 4-½" wide .
These come without the Harley mount shown in the first 2 photos but have the OEM Triumph Splined adapters for front #8841 (#8813 will also fit front Triumph and is what I have on my my bike but I believe they are a looser fit, I have the different rear too if you want them #8808).
Both #8841 and #8808 list Triumph Rocket 3 on the application list on their packaging.
Do you find that footpegs are lacking in support but you don't want the bulkiness of a foot board? We have the perfect solution! These compact boards combine the size and convenience of a peg with the comfort of a full-sized floorboard. 5-½" long x 4" wide and styled to complement our Premium and Trident lines so you can still ride in comfort without sacrificing style. Utilizing splined adapters, the boards can be positioned forward, back, or center at almost any angle. Also a great option for Driver Cruise Pegs!
