The models include the KM131 4 speed transmission used in Dodge D50 trucks from 1983-85, the KM132 5speed, 2wd, transmission used in Dodge D50 trucks from 1983 and up, and the KM145 5 speed, 4wd transmission used in Dodge D50 trucks from 1983 to present. These same transmissions are found in Mitsubishi trucks also. These units are similar in design to the FM146 except that the bell housing integral to the main case. There are many design levels of this unit and it is extremely important to get tooth counts and input bearing numbers before ordering parts. There should be a model number and alphanumeric code stamped on the bell housing which helps to identify the units. ----- ------------------------------------------------------------------------ Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 http://creationwiki.org http://johnmeister.com http://wagoneers.com http://fotomeister.us ------------------------------------------------------------------------
