I bought these lightweight pulleys, belt and seal brand new but never installed them. I'm moving on to other hobbies and am selling the car so I have no need for these. They are NOT the underdrive pulleys, they are stock sized. These weigh less than half the OEM parts and have proven results. Comes with a brand new Gates belt and oil seal for the crank pulley. Asking $225 shipped OBO. Thanks!
