Due to popular demand Scott Drake now offer superior quality "Shorty" headers. Shorty headers eliminate steering system and bell housing clearance issues associated with most long tube and Tri-Y headers. They feature extra thick 3/8" flanges, 12 gauge 1 5/8" primary tubes and 2.25" ball and socket collector for ease of install and a leak free installation. Includes necessary mounting hardware and premium gaskets. For 1964 through 1970 Mustangs with 260, 289 or 302 engines. NOTE: 64/65 cars may require either 66/70 motor mounts and brackets or 1/4 inch spacers on stock mounts for proper clearance. 67-68 manual transmission cars will have to modify the clutch equalizer bar. These will not fit late model 302 "P" heads. EFI cars require C6TZ-9430-RCO2 Reducer Cones.
