Those are the ones,one size fits all. Most ford 9 In. use a 3 inch axle tube. early Mustang and I think fairlane with the 271 hp engines had smaller tubes so the 4 spindle U bolt air tool could torque them, the same as for 6 cyl mustangs, on the final assembly line. double check the spring center bolt and make sure the hole in the perch is big enough. If needed drill out before welding. My Brother had a fairlane he used to drag race and had the rear mounted traction bars, he used to break the spring tie bolt , after 4 replacements he drilled out the spring bolts holes and used the bolts spec'd for a full sized Galaxie.
