A really good labor price, from a good shop that has done it before, would be $500.00.
Go to RockAuto and look for the 9 3/4" clutch kit, and look for a sell-off. But if none are available, it will be around $250.00. But you can wait it out and check weekly and a low cost kit may come up. Don't worry about the brand of the kit as they all originate as a Valeo kit that has been re manufactured.
You are now up to $750.00 and that is predicated on not having any issues with:
1. getting the studs in the cast iron manifolds to release the nuts without breaking the studs
2. having all the sub frame bolts come out of the body mounting points, probably only the rear units need to be removed.
3. the flywheel not needing to be re surfaced, which it will, so there is another $50.00 or less.
If you try it yourself, take it to the best exhaust shop and have them loosen the cast iron exhaust stud nuts, you need a lot of heat and know how to get the nuts off, and it is something you definitely do not want to do yourself.
Pull back your front carpet to expose the huge plastic plugs in your floor / cowl and after popping them off, soak the subframe captive nuts with penetrating oil, every day for about a week.
When you get to the part where you are lowering the sub frame, make sure your DIS unit does not get mashed into the shock tower assembly on the passenger side.
In conclusion, plenty of people have performed a clutch change in their driveway and accomplished the job without drama. But you are going to have to do a lot of research on this site and other sites, and as noted, there is a VHS version of the job from SHOnut Performance. Snoop around the forum, gather your information, and good luck.
