X2 and your looking for an "A" or a "D" in the 5th digit of the VIN number if its factory 440, being 78 Its not factory 383 even if it has it stuffed into it the VIN is on the drivers door or door pillar it will look simular to this one. if its factory 440 and is decent shape DON'T JUNK IT!!! put a tranny in it and resell it if you don't want it to fund you power wagon build.
