help with 88-98 doors

my doors sag and the pass. door wont shut all the way or when it does itll come open a little. so i bought pins and bushings any idea of how to get the old ones off? i hate that the doors dont bolt on. will this fix my problem?

it should. I j ust used a flat piece of metal and put it on top of the old pin and hammerd it out. Then got'er in place with the new pins and tapped'em in. Any body shop will tell you exactly how to do it. I learned by looken and hammering shit until i figured out how it worked. I don't suggest you just start hammering shit tho. But make sure you align the doors when you put the new pins in. Good luck with it.
