1996 GM Drivers Door Sagging-Help!!

My 96 GM drivers door is sagging down , so, I really have to slam it to close it. The top hinge pin ie worn out. I can lift the door to where it is subpost to be when I open it & can see the free play in the top hinge pin. Are there any repair kits that just have a new pin or sholder bolt I can install after I sheer off the top of the hinge pin ? Anyone know ? Or have a good home remody for the door sag problem rather than having to replace the top door hinge with a new one ? Thanks for your help. Dan in SJ.
