Floor Repair

[Bluegoose972]

In the process of cleaning up the underside of my blazers body before I mount it back on the frame. I noticed several small stalagtites (spelling?) hanging down around the rear fender wells. Upon further inspection, that is where the previous owner used bondo to fill in all the rust holes and reshape the bed area flooring. In a nut shell, after poking about 5 holes through the floor with minimal pressure, I'm sure that the floor is in need of much needed repair from rust. Does anyone offer a kit for the replacement of the rear area on a blazer? I'm really looking at replacing the whole back area including the wheel tubs. Most places offer the tubs, but I'm not seeing anyone with bed panels.

Any suggestions?
