This is a huge job, not for the faint of heart.
I had several problems with the original clutch on a car with ~113k miles. Hard shifting, chattering clutch, and the throwout bearing would whine when the clutch was disengaged.
I decided to go with the SPEC stage 1 clutch from American Muscle. To put this much work and money into a car, I wanted good quality American parts.

Obviously, all the standard car safety rules apply here; block the wheels, use jack stands, use the jack as a backup safety, wear eye protection, etc.
