I think you just need to have some common sense when you look at the mounting system the slider uses. My no cuts used a beefy aluminum mount that picked up a few of the large frame bolts. It was obvious they'd hold up.
heres a shot of ones that it takes two seconds to realize they wont work in anything but a parking lot tip. Thin aluminum strap and it picks up small hardware on thin frame mounting tabs and the long stand off is a huge lever arm that will bend anything the slider is attached to.
