These disconnect systems are solid construction, and a heck of a deal. But the part listed for Harley Dyna does not fit all Dynas. I have a 2011 Super Glide and it required a different kit, the VK1000. My mounting holes were 10 3/8 inch apart. Viking customer service fixed me right up, but I could have saved myself the trouble by calling them first to make sure I got the right mounting system.
