Im just about set to cut the rear 3/4 tub off and lift the cowl. Is there a trick to the 2 mounting bolts attaching e cowl. 1 snapped, and the cowl is free on that side. The other boot broke free, but just appears to be spinning in the bracket attached to the bottoms of the cowl. The bracket is pretty much rusted and I can't feel a nut inside. Was something welded I place and did he weld brake free? Any tips on what I should do?
