ps: will post a pic as soon as I get the car.
No tune is required though highly recommended, now who does that tune..................oh boy.....just search and read, no need to bring that up in another thread. There are countless threads on pulleys and tunes that will keep you busy for a long time.

BUT my 2 cents of advice is whoever does the pulley should have some experience with this work. While it not difficult many have have not gotten the torque specs right and as a result the crank pulley backs out and the pulley usually walks itself off the end of the crank. This most times casues keyway damage and an EXPENSIVE fix!
