Don't know too much about the earlier Mustangs, but just purchased a 1966 Fast Back (to later re-sale) and have some questions. The Door tag reads: 63B Z F8 19E 72 6 6. I have already decoded this information along with the VIN (it's an original 289 2V C Code Engine car). It should be a deluxe interior from what I deciphered, but this car only has the wood grain steering wheel in it as of now. The seats are blue - wrong color for this car (and no running horses), so they aren't original, the original doors are missing the courtesy lights, but the factory holes are there for them. The glove box door and instrument cluster is black instead of wood, so someone has gotten rid of alot of the desirable stuff. My question concerns the front disc brakes. Everything looks normal and appears to be original. The brake pedal and accelerator pedal have the stainless trim around them and the brake pedal has the center stainless emblem on it that says "Disc Brakes". Could this car have original front disc brakes? There is no booster, but the screw on type lidded master cylinder is much larger than what I typically see on other cars with drums up front. Any other ways to tell if original to this car? The other question is the glass is all tinted and says Sun-X on each piece of glass. There is no under dash air conditioning in place right now. Could the windows have been ordered without A/C? Is there another way to tell if it came with A/C besides looking for mounting holes underneath the dash? It was built in and has a DSO code of San Jose, rumored to be from Arizona about 10 years ago, so I don't know if tinted glass without A/C would be typical out west. It's in Illinois now and the winters haven't gotten to it too badly as of yet. BTW, found this car in a barn and it had been sitting for the last 10 years with lot's of bird droppings on it. Had to stop at the first car wash on the way home and drop $10 worth of quarters into it. After it was washed, I can see at least 5 other colors this car had been other than it's current burgungy. (Original color was Medium sage mettalic) The washing alone probably tripled it's value, what a site it was! Anyway, just curious to the brakes and tinted glass. Thanks for the time, it was a nice find and felt like sharing a little.
