Finally I was able to put some time on this car. The front of the radiator support shows that it wss sprayed black behind the grille. Even on top of the bracket that holds the little hook!
The battery tray was bolted to the inner fender with two different kind of bolts. The tray with a narrow bolt and the brackets with an ordinary bolt. As you can see the tray still have the greenish primer on the backside which mean it wss mounted when it came to the painter. There is still some trace of yellow paint on it.
I have included pictures from an engine bay that hasn't been molested too much.
