99 Fatty SL DIY Boot replace and regrease?

Anybody ever do there own boot replace and regrease of the the bottom race area that is under the boot area?

I've never done it, and don't want to get into the internals of the shock, but I think this is a reasonable DIY project.

Any experience.

Holds air, still is smooth and I'd don't feel like shelling out the cash for a rebuild and everything on a commuter bike if I don't really need to.

Also, what PSI do you run your Fatty SL at. Its so old I don't remember. I think it was recommended at 70-80% of your body weight. (Ex: I'm 155 lbs so around 120 psi)
