4-SPEED TOPLOADER IDENTIFICATION
        On the passenger side 
          at the front edge of the maincase there is a small metal tag with
          a HEH or RUG number. This is a list of tag numbers that
          decode the transmission. The lower number on the tag is the serial
          number of the transmission in the order it was tagged, it has nothing
          to do with the serial number of the vehicle the transmission is
          in.
        If
          you do not see your tag number listed here, please check our  Toploader
            Imposters page.
