Opinions Wanted - What clutch parts to buy and can I do it?

I would start with 4 jack stands, you can get by with 2 but it makes it easier if you raise the whole car. You'll need a clutch disc, pressure plate, and throw out bearing. You should resurface the flywheel also, you may be able to take it and have it done while you wait. You may need some 90 weight for the trans, typically it runs out when you pull the driveshaft. It woud be nice to do the u-joints while the shaft is out.
I don't see why you couldn't do it in a day. Good Luck!
Or some good ramps. Don't forget a new pilot bushing. If you have a good local clutch builder, I'd go that route but you might also check with NAPA. I've gotten some good deals with them lately on other clutches. Came as a set with everything you need. It even had an alignment shaft! You'll need some basic hand tools.....wrenches, sockets, extensions, pry bar, etc. You'll need a pilot bushing puller or carefully use a small sharp chisle to remove the bushing. You can reinstall the bushing with a hammer and socket about the same size. A tranny jack helps but the two of you can manhandle it if you're carefull. If the trans is original, you won't need to worry about 90wt leaking ouf of the tail shaft, your year still has the bolt-on flange. You will want to get a plug for the speedo cable hole though. If it's a later slip yoke type, and you're planing on new u-joints, take the yoke off the driveshaft first and slide it back in place while you wrestle with the tranny. If you stick it in gear when you reinstall the trans, it will help having the yoke in place to get the input shaft splines to engage the clutch disc splines. Just rock the yoke while you wiggle the trans up to the bell housing. Check your clutch linkage, boot, and fork condition too.
