try nicksclassicparts.com if you are loking for TTi's. Just bought a set and got what I consider to be a good deal on them. Best price I could find anyway. Installed them on my 74 dart that has a transplanted 360 and they fit great. As for Quality. These are some of the Heaviest headers I have ever picked up. Built like a tank. I know a lot of people think they are not worth the money. In reality, almost everyone who chooses to restore a car is spending way more than it would cost to just buy one that is an older restoration. But wouldn't be near as much fun to drive something some one else built. Don't get me wrong. I bought a lot of parts at the boneyard to save a buck, but the headers are one thing I would not compromise one. I bought the C4 Option. everything except polished.
