Tailgate Hinge problems of the 1997 Chevrolet K1500

I have a 1997 chevy silverado 1500z71. The galvanizedbraid-steel tail gate support hinge used to support tail gate broke. They had a recall on the 1999-2000 for the same thing. It should have been on the 1997 also. The official NHTSA recall notice says this is dangerous and they will replace them on the 1999-2000 models the need replaced on the 1997 models also.

I lowered my tailgate for my dogs to exit and the cables broke, my dogs slid out onto the ground, and the tailgate was damaged by the bumper. I had the tailgate fixed at a body shop, painted, and reinstalled. As for the cables: I replaced them at the local dealer. They are starting to corrode again.
