when replacing a clutch,pressure plate, or any of that, i would always go with brand new parts. there are too many variables that could go wrong with buying used parts and is really expensive to fix if something goes wrong.

there is a sticky in this thread by westcoaststyle at the top of the Civic/Del Sol/EL forum called 'Online Resources'. If you are looking to do this yourself, he has a write up in that thread that covers how to change out a clutch.

Its about halfway down the page under Drivetrain and it has bunches of pics and text. Grade A. Kudos to Josh

Hope this helps!!
