If you have the ktm/husky front fender I'm sure a shop would know what to do....you can see the spots where the new holes will need to be drilled if you take the existing fender off and place the new on on there.Use a sharpie or a paint marker or a scratch all to make the marks in the triple clamp then simply drill them out to whichever size of bolt you use I stuck with the metric threads I believe a six millimeter by 1.25 is the threads I would have to look to see for sure that's just going off memory it's an 8 mm hex head bolt then run the tap in there and clean out threads when you're done.... Also on the underside where the two bolts will go I believe I had to drill new holes in the plastic itself not in the triple clamp I utilized the existing holes in the triple clamp on the bottom side
