Hello was the hood bird standard equipment on the 1978 Trans am the dealer invoice on a car I am looking at purchasing doesn't show it as an upcharge or option, so I am wondering if this car had it originally or does a guy need the build sheet to determine this, the car is martinique blue 4sp W72 Ws6 fisher t top late may early june 78 build from van nuys plant, any facts on this would be greatly appreciated.
