Ok this may sound odd, since it's coming from a newbie. BUT I can't seem to find a set of headers for my truck. Here's the specs 79 f150, 4x4 with a 302 windsor engine swapped in it out of a mustang. The engine seems to be the problem, even though they did come from the factory with 302's. So far the only thing I can find is a 1980 4x4 header, but that's the newer body style. The guy I bought if off had headers, but they didn't clear the front driveshaft. I also had some mustang shortys on it, but they hit the clutch pivot. I'm just curious if anyone else has ever ran into this, and hopefully has some ideas!
