Todays update; Broke out the sawzall & cut out most of the l/s outer wheel house, & started drilling out the spot welds where the inner support structure & the inner & outer wheel houses are all welded together. Removed the outer wheel house where it is welded to the l/s rocker panel & found broken glass & what looks like a rats nest of insulation inside the rear of the rocker panel. I took some pics & will try to get them posted over the weekend.
