You donot have to pull the hinges - use a floor jack to support the door - assistance is always a plus - then pull one pin at a time - place the bushing and install a new pin - the do the other

Saves re-allinging the door - hinges  to the frame and blue language

where do I buy pins and bushing?

______________

Here is how I did mine

Napa, Kragen, or AutoZone should all have the parts you need.  I agree with the link Suncountry provided.  I undid the hing because I never thought of filing the head but what the heck.  Also I really do recommend a second set of hands and something to set the door on. A floor jack works great.

The generic bushings are exactly like the original GM ones, which is a good thing since GM has discontinued them.  I don't have any experience with the pins.  We get $18.75 for a kit for one door (less you forum 10% discount).

I use a cherry picker or rope from the ceiling to support the door, so you don't have to worry about it slipping off the jack or tipping over.

I just bought some pins from autozone. They appear to be a little longer then the originals

any suggestions?

The replacement pins are longer.  So, put the top pin in from the bottom.  Also, the door springs have opened as many times as the doors and are most likely worn out.  They are much easier to replace with the pins out.  You will have to slide the doors back an inch or so to put in the new brass bushings so this is a great time to replace the springs.  Spring replacement is not fun and even less without the extra room created as you slide the door to the rear.  You will need the spring replacement tool.  RIK's has the springs and the tools.  Spring replacement can be accomplished with the door in place but very close to impossible and very difficult withour chipping paint so mask off the edges first.  Ask me how I know!

if you put in the top pin from the bottom it will not slide out?

______________

They will not slide out; They should have little spring clips/stops which prevent them from coming out.  Don't worry.  The other solution is to take the hinge loose from under the dash and put the pin from the top.  Trust me, that is to hard.
