I found this tip from our Swedish TLR team driver, Otto Ausfelt, last year at the World Championships in Finland. He simply drills the front body mount out with a 1.6mm drill bit 90 degrees from the original hole allowing the body clip to insert from front-to-back instead of side-to-side. I suggest removing the body mount and drilling it while holding the body mount in a small vice or a pair of pliers.
Race on....
