    28140 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Fit perfectly! You Pontiac people know headers suck. Well, I finally found a set that drop right in and bolt up...WITH ALL THE BOLTS! They need put in from the bottom but no big deal. This on a 68 Bird with power steering and air conditioning. Congratulations Hedman on getting it right. I now endorse headers for Pontiac. Oh, ground clearance is good too. I especially liked the ball and socket style collector. Gives you a fudge factor

    Rated 5 out of 5 by from You cannot beat these for the money!! Good headers, fit real well, all hardware included
