Drop some pictures.. I left the tray black when I redid the engine compartment. I did have to get a second mounting bracket. The car had a trunk mounted battery when I bought it. The 64 parts book and body manual showed two brackets where the kits only provided a single one
I got two brackets with the battery tray (separate purchase). I have two other 64-65 Valiants that have battery trays, and both have two brackets, so that is what I ordered. Those trays are so old they have no paint left.
