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!
