I ordered one too. I am mounting it on the painted radiator cross frame (to the right of the hood latch). I am complementing it with two black anodized radiator support disks (a/k/a beverage delete)- one engraved with "Challenger," and the other with "SRT." It should look sweet.
The name plates are available from Billet Technology. I rec'd mine on Saturday. One for each car. They are nice!!!
Build date can be found on the driver's door tag and on the inside of the trunk lid to the right of the latch. You have to look hard to find it.
On the door it says MDH, stands for Month, Day, Hour. It is a sticker on the door.
