in the US Dodge and Plymonth sold these as "captive" imports from 79 to 83 and then Mitsu got to sell as the mightymax in 83, when the plymonth arrow truck was discontinued. The US truck benches were cut out for the shifter - odd yours is not, maybe the seat was swapped. There were dodge colts and plymonth arrow cars here with 2.6 motors (front engine, rear drive), and sapporos / challengers also - I am not sure what they were called outside the states. There are also 2.6 motors in some front drive mitsus that have been parted out for use on starions - the magna intake comes to mind.
