i gotta agree..the picture doesnt show anything that i have not seen on my 84, and i can whack the hell out of the area with a 3lb sledge, and SOME rust will fall off, but it isnt a "GONER" in any way i can see.
the cross member behind my back bumper is just about rotted through, but Im gonna weld a new pecie of channel before i install my iron pig bumper.
my feel about rust its keep it in check, the best you can. i installed a hot water spigot outside , and i spray the underside of the truck after every snowstorm.
oh, and i also scraped and por-15'd the @&@&@&@& outta' my frame this fall.
