Early A-Body battery tray

The battery box in my vert is aftermarket and crap. What was the original battery box configuration in a '63 Dart? It looks like, from the frame rail, it had 2 45 degree under tray brakes and did not have the one that went from the top of the tray to the top of the inner fender like later Mopars (deduceded because there are no holes in the inner fender for that bracket).

Thanks,
Jim
