I have a set of stage 2 headers for 68-72 GS. They are driver quality, as they are painted silver. I think they are TA, but am not positive. I got the headers as part of a package deal. I have not had them on a car. I will post pictures Monday the 11th. The price is $225.00 plus actual shipping costs. They are located in Hesston Kansas. I will look for a part number Monday too. Thanks, Allen PS Please contact me via public forum per board rules. Monday 1:30 PM The only numbers I could find were stamped on the flange, its 4656, which does not match any TA numbers. The pictures will show a few dents, which we all expect on a set of Buick headers have been "fitted". Please look at the pic's and let me know what questions I can answer. The flanges are nice and straight. Alllen
