manual trans swap

    1983 700R4 auto to 1976 SM465 manual transmission swap

    My son and I are planning on doing an auto to manual swap in his 83 C20 from our parts truck which is a 76 C20. The transmission crossmember was destroyed when it was parted out. Questions 1. Is the crossmember specific to the SM465? 2. Will the cab need to be lifted to install the manual...
