Looking for that thing i just had in my hand...
They pop up now and then, a USDM usually runs between 4-6k and the JDM 6-12k. The US ones are all swaps unless you find one of the fantastically rare 1983 (1984 model) diesel Monteros and the JDM's just watch the date code on the ID tag. Go by the manufacturer date not the year model and look for a minimum 25 year old truck.
