Got this done yesterday with a few issues, so I thought I'd give a heads up to anyone who has to try this in the future.
Tools: Drill, 3/8" drill bit, hammer, screwdriver, visegrips, jack & wooden block (later went to a cooler), beer
Weather: New England 35 Degrees F, 20 - 25 MPH wind so it feels like 10 - 20
1st thing I found was balancing the door on the jack was tricky at best. I did the top first by drilling out the top of it with a 3/8". Took the top doorside bolts all the way out, loosened the bottoms. This jack balance trick is iffy at best, so I get the Colman cooler & balance the door on it. It was slightly lower then where the door normally is, so it allowed enough room to get into the top pin. Once the top of the pin was drilled out I noticed I did NOT have a punch. Fine, so I use the new pin to pop the old out. Everything is going too smooth I think. Take the doorside hinge outed the top one first & stare at the brass bushings. Used the screwdriver & hammer to tap them out, then visegrips to start the new ones. I squeezed the grips enough to start them, not crush them all the way in. Trick is to start them so they are even. Finished up the new ones with the hammer & tapped in flush.
Bolt the top back onto the door & open the first beer. Total time for top pin was less then 20 minutes.
So I'm thinking I'm home free. Door works ok, but has a big alignment problem. Seems to sag still, but now when closed. I check the play in the door & find the bottom one is too far gone to ignore it. Seeing how I had everything out already, I figure I might as well go after the bottom next.
Unbolt the bottom hinge from the door, loosen the top. Can't get the drill in from the top or bottom (need to drill out the bottom this time). Called my brother up & finished the 1st beer. He shows up to try to hold the door out of my way so I can get the drill in. Kind of get enough room to start drilling, but it's going at an angle. So in all it is not working too well. We decide to remove the door completely by removing the top door bolts. 30 seconds later the drill is through the bottom. Old bushings out & new ones in faster then the top due to the experience of the top ones.
Total time for bottom one: about 45 minutes, 1 beer.
So in closing, it is not too bad. Took longer to figure out the door / jack balance thing then to do the whole job.
Thanks all for the help, now on to the wife's Pontiac alternator
