This may clear up questions others have, might be useful....or you already know but here's the fender tag codes and VIN decoding information for the 1987 Shelby Z's. Jump in if I'm off somewhere.
So far the best info that seems to apply to the 1987 Daytona Shelby Z's (probably any 1987 TD) is:
http://www.omnilith.net/teamomni/ftag.htm - Great breakdown and explanations
http://www.turbo-2.com/pdf/fendertag.txt - Huge list of options for a 87 Lebaron, but seemed to work for me.
