last week i ordered my r/t and the next day i made some changes by phone and dummy me didn't get a copy of the order until today. well, they left out my alarm system. the dealer told me that they could install it when they recieve the truck but is it gonna be the same system . also does anyone know why they couldn't call and add that option on i mean they haven't even started to build the thing yet and i don't want to have to pay extra when i could get it factory installed. anyone have any advice?
