Distributor hold down, battery tray

Been cleaning and blasting small parts. When I blasted the paint off of the distributor hold down, it appears that it is copper plated underneath the paint. Are they all like this? The copper color would not blast off.



I was going to see if I could save the battery tray, but it looks to be almsot beyone saving, and I have looked in the catalogs and online and my battery tray is not shaped the same as pictured in the catalog, leading me to one of two conclusions, first that they are using a stock photo(the same photo for all battery trays, regardless of model) or second that this is an aftermarket tray, that in the past replaced the stock tray. I'm leaning towards the second.



Anybody have a picture of a 67 Dodge Dart battery tray.

Thanks
