I am selling a brand new centerforce dual friction clutch and throw-out bearing. part number for the clutch is df800075 and the throw out bearing part number is N1714. It fits 99-04 mustang GT's and cobra's. Will also fit later stangs with a flywheel swap. This is the very clutch I have in my 96 cobra. I have it listed on ebay. I will be taking a bit of a loss on it. This is a great upgrade for your mustang regardless of the power it makes.
