fOR WHAT ITS WORTH AND THEY LOOK GOOD AND YOU DON'T HAVE TO GO TO ALL THE EXTRA EXPENSE for different rails and ect.,big fingers and the caplock ,sorry,at any rate check out the Kuryakyn Constellation board #4457 and their Triumph splined adapters #8813. Retail total $225 and you can get them less if you shop the Fleabay. If you have long legs you can also get their 2 inch long adapters #8837 $50.00 and set the boards a little lower than the control rail too. I have this setup on my R3R already.They have another floorboard out too that fits this same splined adapter for the Rocket3.I chose the 4457 as I have a long foot size. If your interested in seeing them installed on the R3R I'll take and send you a pic if you like,just LMK.
