a couple of questions
 

Is there a rebuild kit or something for the hinges of the rear tire carrier? The top rear hinge is missing one of the bushings inbetween the rear tire mount frame and where it attches to the Blazer which is causing a racket on big bumps at low speed. I'm not sure If I'd just buy the bushing/washer or if there is a rebuild kit for it?

What size/thread pitch is the bolt that holds the front access in the skid plate closed. Its hanging open right now since the bolt is missing.
