I use that mount and after 100+ miles it works great. I had to file my trucks and the set screws came loose so I was going to get it welded to my trucks but after some research I found someone else who had the same problem used jb weld. I know that sounds week but it has not come loose yet and I did it when I first built it. I rode it a couple of times, the set screws came loose and dropped down (that's why its all scratched up). I tried thread lock but it didn't hold. JB weld! lol. I would say if you had to sand your trucks, take your time and make it a tight fit and you might not have the same problem.
