Spark Plug Heat Shields- Zinc Plated?
I have my original spark plug heat shields for my 72 Nova. These need to be replated. But i dont know what kind of plating was done to these when made new. Was it a silver zinc plating? Or was it something else? If so who knows a good company that does replating for these heat shields? Any input is very appreciated.
