If you want to know the born date with the time down to the second. JUST LOOK UNDER YOUR TRUCK. There is a sticker on the drivers side. On the frame just in front of the rear leaf spring mount.
Our trucks have the month on the inside of drivers door also. Noid is talking about he exact time and date the truck rolled of the assembly line. I have to look again, but I think mine was born on 5/10/04 at 8:27:46. I will verify the time again.
