How is the Motor-guide mount attached to the bow from the factory? Had a rough weekend on the CA delta with non-stop 4 rollers, got home and my MG mount was loose. Tried to tighten the philips heads on the top side, and they were just spinning and never got tight? Not sure if they are screws or machine bolts.There are what look to be rubber isolator pads, are these some sort of expansion anchor through the fiberglass? Or are they a through bolt with a nut on the inside that is spinning when I try to tighten the bolt?Any help would be appreciated. Its a 82lb tour edition on a PIV.
