I added the Bender model to my 2000 Vmax after I "tweeked" the tunnel. They add alot of stiffness and are fairly easy to install, removing "loose" rivets is the toughest part. Don't even know they are there now and I had a second small incident and it held up great.
On my 97 SX that I picked up used the rivets were worn all the way through the foot rest area so I added a piece of aluminum similar in size to the threaded trailing arm attachment plate on top of the foot rest and used 1/4" stainless bolts with a pan head/torx drive to attach. I haven't ridden it since adding the plate on top but they don't seem to interfer with my feet.
You could use a hex head bolt and would have added traction. I temporarily had one in my set up but didn't care for the traction in that area so I made sure to replace it with a pan head when I had the chance.
