While taking apart my blazer i noticed a lot of rubber gasket ? type of stuff. It seemed to be in between the back floor and the wheel wells, and in between the floor to the cab portion of tub (the floor sits on top of the cab portion). It's some kind of rubber seal. I ask be\cause it actually worked at keeping out moisture. I have no rust in these areas. Is this something that should be replaced?

Most likely what you are refering to is "seam sealer"...

If it's like mine, the underside is wavy to match the bed, and the top side is flat. Without it no more flat floor in back.
