The headers are Headmans, which I bought from Mustang II speciality shop..the link is on the MustangII.net site. They were not easy to fit...after the install...I heard that Hooker made headers for the Mustang II 302....so my advice is if there is no luck in hookers, then get the headmans....I just am not a big fan of the way the headmans fit and one tube is under the x member. Also a note...if you install the headmans then
tranny coolant lines will have clearence issues if aftermarket prebent..I had to use my old crapy ones.
