I have a 67 GTO with 1971, 400 engine. The intake manifold number matches the one for 67, the quarter Quadra jet that’s on it number say it’s off a Chevrolet. It is missing quite a few parts, the primary flapper, secondary linkage, and it is slightly damaged. I would like to replace it with a different Rochester Quadajet. The number on the current carb is 7037263. I see a lot of cheap Chinese reproductions. I have no idea how good they are. I’m also Looking for a rebuilt, original quad jet. Any suggestions you have would be greatly appreciated!
