Need help fishing a dropped wrench. Was working on the rear side window on a 68 Dart and dropped a 7/16 wrench down the inside of the quarter panel. It slid perfectly down the side between the inner rocker panel and the quarter panel. The wrench went right down to the belly of the rocker. Any ideas fishing it out. Tried everything I have or learned in the past to no avail. Magnets coat hangers, wire. The gap at the bottom must be the same width as the wrench. Need to get it out or may have a permanent rattle. Ideas please, or am I the only idiot who has done this. Thanks.
