Or are you looking for all the codes, including the factory options. If you are including those, than I don't know who could help you.
I don't have my original or a replic build sheet. What I have is a Mustang Red Book, and a copy of the 1966 Mustang accesories list. Unfortunately, neither of them have the price of the Sprint 200 package which is what I am looking for. So, if anybody has the price of the Sprint 200 package, and the accesories codes, please post them.
