Looks like you have the wrong bushings. the old one can be drilled or driven out and the new one can be pressed in, i use a bench vice. back in the day we used the knurled ones to repair hinges that had worn excessively (hole egged). As to your hinge pocket problem you just need to remove the pocket by drilling out the spot welds,repair the pocket and reinstall. Sounds easy if you say it real fast,actually not that bad of a job
