Hi All:
Ha! Where do we begin?
What pops to mind, besides the excessive amount of bondo over rotted-out sheet metal in the body tub, was the "PO" (numb-nuts) using regular household carpet insulation underneath the front floor mat, but not plugging the drain holes in the tub.
So, when I pulled the floor mat out there was all this soaking wet carpet insulation, and a rusty floor pan.
Good times!
Alan
