Well, got my Summit G9041 headers in the other day along with their universal 2.5" x-pipe kit. For being such cheap units, the headers are amazingly well built with extremely thick flanges at the head as well as the collectors and very good welds. Two of the tubes are also dimpled for steering box and starter clearance which wasn't apparent in any of the pictures on the website, was quite a nice surprise. Being that they don't list any headers for the Cordobas, I looked them up using 74 Charger thinking that it's the closest I'm going to get. Lo and behold, the first car listed in the instructions is 75 Cordoba with the 400 lol. Might have to do some modification to the shift linkage being column shift, but as long as they fit ok everywhere else I'll be happy. One last note, looks like they're built for Summit by Flowtech as they came in a nice big Summit box, with Flowtech stickers inside lol.
