I didn't get it done all at once, because I had to stop several times to search for tools that I didn't own. You'll need a big socket to take the clutch boss nut off (I think you need a 32 mm, but i'm not sure. I can find out for you tomorrow exactly what size it is. If you have, or have access to an impact wrench, that will make it easier for you to get that nut off. If not, you can get it off with a ratchet and breaker bar, it just takes an extra set of hands and some clever use of 2 screwdrivers and another bar of some kind, to hold it from spinning. Scraping off the old gasket from the cover will also be a little time consuming because they seem to be glued on there pretty good. Figure on spending 1 or 2 nights on it to get everything done right.
I also forgot to add originally, you should also have a torque wrench to put everything back together, and some sealant to use in addition to the gasket. I used blue RTV gasket maker/sealant from the auto parts store and it worked perfect.
