Chrome console top plates need refinishing-powder coat?

If it indead Chrome, muratic acid will strip it. But then you have the Bright Nickel that will be hard to strip. Under that should be a thicker kayer of Copper, which will require somelse to strip it. Plating shops will use electrical current in sulfuric acid. The top on my 68 consel is non magnetic which says it pot metal as mentioned above. Your best bet is taking it to a plating shop that does pot metal.
I started as a plater in the 60s and spent the last 30 years running plating shops of all kinds specializing in precious metal, so I speak from experiance..
