It is possible you got the wrong headers, that look similar. But if they are in fact for a 200, there is a good chance they will fit, reguardless of the model they were made for. I know that the mustang, falcon, and bronco headers are all the same, even tho the part numbers may be listed as different. There were also other manufacturers making headers for the 200 back when our inlines were still in production (remember Cyclone and Hedman), and then there is Hooker, so they may or may not be Cliffords at all, maybe they just thought they were. They could also be custom fenderwell headers that were used with fiberglass front clips. I'd like to see some pics if you wouldn't mind posting them or e-mailing them to me.
