Watching Army's thread is making me feel like a piker.
I still haven't decided what to do, but this morning I ordered a replacement floor pan for my driver's side.
After wheel grinding, both pans on the passenger side look good and the driver's side rear has only one tiny pinhole, maybe 1/4" by 1/16". Plan to use POR15 to stabilize these.
On the driver's front? I guess I'll have to wait to see how long it takes for delivery. But I may be forced to descend the rabbit hole if I want to show my face around here.
