I have to admit that now because I'm not doing this for the Department of Defense and am only doing it for fun I have lots less anxiety.

EDIT:: I ended up painting the windows of the JLTV black and cemented the doors shut because I couldn't figure out how the dashboard fit. NOw I have a problem with the air filter intake on the JLTV fits on the body, but because i'm not trying to wow anyone I have WAY less anxiety.
