Hi! I just bought a TTA from a forum member. The wife is currently driving as we drive this beast back from Columbus, OH to Pocatello, ID so I'll post and ask some questions. First- I think I have car 851 and not 771. The PHS letter says 771, but I looked myself and the VIN matches up with 851in the list. The VIN is 243130, so I think PHS is in error (one or the other). Car came from Bob Fish Pontiac which also matches up with 851. This car is a time capsule! We will be replacing the cracked wing when we get home. Which one? I was thinking this one from Classic Industries: 12397143 - 1985-90 Firebird Formula Trans AM GTA Aerowing Wrap Around Rear Spoiler.
