i purchased an old GMC COE with no title and am trying to decipher what it is i actually got for my money. Spanky was nice enough to fill me in that it was a 350 series and by the picture that it was either a 52 or 53. i was looking at a 52 GMC 5 window COE on ebay and noticed the outside door handles twist while mine are push button. Does that make mine a 53? my COE, however, is not a 5 window, but rather a regular cab.
