Hedman confirmed that something was wrong with the passenger side. So I have returned them, and Jegs sent me the Hooker 5903 by accident, and you are correct the Hedman do fit the best... I have returned the Hookers and just purchased the Year One manifolds. I gave up at I just can't justify the cost of TTIs, even though the wife was helping me and saw how bad the fits were she gave me the go ahead to get them. In the end it would have saved me about $80 in shipping.
