1994 tailgate hinge threads broke off? how repair?

The screw that that goes into the the body holding the hinge up came out and looks like the threads broke off. looking at the other side it looks like there was/is something mounted there? anyway I am not a body or metal person. Can someone tell me how to fix this?

Thanks

If you could post some pics it would help.

ok will do. I have to finish checking out an putting back together my phlenum on the buick. then figure how to put a pic on. but I will thanks
