Ah, ok, so it's not a good idea to take the hinges off and work them over on a bench? I'm wondering if I need to go to a body shop for this, I don't have those kinds of tools here.
You only would need to remove the hinge that attaches to the door after getting the old pin out, the one on the body stays unaltered which is the hard one to remove anyway.
A drill press makes it extremely easy, and if you don’t have one get one if you have the space. Doesn’t need to be anything fancy, I’ve done some really crazy things with my cheap Skil press, including those. Same goes for a cutoff wheel, the harbor freight one is cheap as dirt and there’s always coupons for it. Those two things are really all that’s necessary
I also am a proponent of removing the fender to do the hinges, access becomes ample without it
