Ice age was supposed to send me some hifax bolts with my order, but didn't. They then suggested I use Polaris bolts. But being a different thread pitch, I'm not going to re-tap them because of the type of material used on the rails. Won't hold up IMO. They then suggested I use a bigger bolt and re-tap it. Too bad the material thickness is already maxed out with the bolts they currently use. Does anyone know where I can source these bolts? Grade 8 torx flat head
