i just got a 87 dodge d150 the other day and am trying to a little research on it.from my understanding is that it is a 87 dodge d150 le with a 318 2 barrel carb in it.it was manufactured in 12/86.i did a basic vin search on it and it said that it was a 87 dodge d150 custom/reg cab/royal/se.my question is can anybody tell me what all this means and whats the diff between le and se.also what is a royal?it has p/s,p/w,p/l,tilt,c/c and it is a short bed.
