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.
