Printed this out, checked these areas, and sure enough they weren't doing so well. One rear side seemed to be mostly through for about a 2" length. I turned away from the Jeep and actually ended up bumping into a potentially blockbuster deal shortly after, as fate may have it (we'll see on Saturday) ...but for curiousity sake ...how big a deal is this? The rust was through where the spring shackle, rear bumper member, and the frame member that holds the body up all come together so I'm assuming it's important that this area be strong and structurally sound? Is it repairable or pretty much fubar when it gets to this point?
Thanks again!
