I told you someone would take up my slack. I wasn't sure about the 64 but was right on the 55-62. If you get a good pumpkin the job is super easy. Onr thing I forgot to tell you. When you take the enclosed shaft out you want to be careful because the housing will rotate to the "ground" because it has nothing to keep it from doing so. Mine did and all I did to correct it was install the "new" pumkin in the housing and jack up under the new rear third member under where the drive shaft will bolt up.Set it (rear end) to the proper angle and weld the rear support at the springs. I hope this helps. Steven
