Giving 1 star for the fitment... Quality is great as far as looks and durability! However, it says these WILL fit a 68 Impala which is why I ordered them... Finally got my engine in today and had to remove them because these do NOT fit a 68 Impala!! The driver side knicks the steering box, there's no cutout to clear the temperature guage sensor and the flanges are so close to the drag link (3in to be exact) that it is nearly impossible to put any type of exaust on.... Just wish the description would have been a little better but I've had them long enough that I can only hope i can find someone to give me a 100 bucks for them so I can recoup some of my money... I'm gonna assume these are meant for strictly pickup trucks and not cars!!

Finish on them were a little sloppy but fit well which is more important. Overall good buy for the money

Good quality headers. They line up like they should and fit perfectly. And come with everything you need to install them.
