While continuing disassembling under the hood some newly models of bolts were found. I have only seen black phosphated bolts holding the battery tray. This car had silver cad bolts!! This car is untouched and never been apart. Assembled in Detroit.

Anyone seen that before?

I always thought the battery tray was painted at the same time as the engine compartment. So wouldn't the bolts have been body color? They may be been black phosphate or silver cad depending on the assembly plate/supplier, or whatever was on hand underneath the paint, etc.
Or am I missing something here?
