Lee,
More than likely, all you need to replace is the throwout bearing, teaser spring, clutch plate, and the anti-rattle springs.
Some will tell you to not replace the springs, but I like to, so the clutch plate won't drive you crazy with all that rattling.
It is not all that difficult to rebuild the clutch, just be careful.
I always place the clutch shaft in a vise with the plate against the vise jaws, using two or three layers of cardboard to keep from scarring the shaft.
Also align the spirol pin with the slot in the vise jaws so you can drive out the pin.
Tighten the vise (not super tight) to hold the shaft. Take a large hammer and a brass rod or a piece of hard wood and drive the shaft down just a hair (about 3/16 of an inch) to release the pressure on the coiled spring pin.
You can then drive out the pin and release the vise. Just be careful, the clutch and shaft will jump up about 3 inches.
Don't have anything above the shaft, that would hurt!
After you assemble the parts, you can put it back in the vise with the cardboard and tighten it again.
Then take the hammer and brass rod/block and drive it back down a hair, in order to drive the coiled roll pin back in place.
Make sure you align the slots/holes in the plates with the holes in the shaft, so you can drive the coiled pins back in.
