12 bolt rear spline posi

  1. 12 Bolt posi unit

    Transmission - Rearend
    hey guys, do you know what car or truck I can keep an eye out for in the junkyard for a 12 bolt posi unit? This is going into a 1966 Chevy Caprice. Also do you know what the spline count for a factory 12 bolt rear end. Thanks fellas
