I'm at work, so I haven't access to my notes. Chuck Melton's web site has a decoder. I cannot access it from work, my employer's internet filtering blocks access.
heres the URL for Chuck's site: http://geocities.com/provamo72/
The VIN has very little information in it. The color is not specified.
This is how I "remember" the VIN info decodes:
TH = where it was built (Modena)
PN = model (Pantera)
N = month built
U = year built
05318 = sequential chassis number (first chassis was 01001)
I can tell you by the chassis number that the car is a 1973 L model, I'm going to guess it was assembled in April 1973.
