I reported my 85 jimmy stolen.. I found it and it looks ex try the same but the guy took all the gmc signs off and put blazer and chevy logos on it..smh. He changed the vin on the dash and it says chevy.. So I need to know what I need to do or what info I can get off the truck to prove ownership. I have the original title and he doesn't have squat.. where are the hidden vin locations does anyone have an idea?
