Here's what I did. I had a bar clamp mount for my GPS. I used the straps on the back side for more support. I attached the relays for the lights to the bottom bolts.
I have 30mm bar risers and everything fit with some minor tweaking. I left the threaded longer riser blots installed in case I want to remount the bar for a roll chart. The angle of the dash works for me both sitting and standing so bolted solid should be okay.
