Bronco II Manufacturing Date?

[jdm_farmboy]

I've got a part that I'm buying that has 2 different options based on truck manufacturing date. So, how can I tell when my truck was manufactured? It is a 1986 Ford Bronco II 4wd with a 5spd.

your door sticker or vin will tell you what mouth of what year it was made in.
