Electronic voltage regulator to fit 67 factory housing

Does anyone make a good electronic voltage regulator that will fit under the old style (67) factory housing?

Thank you for your help in advance.

The last ones I bought from the parts stores were solid state electronic several years ago.

There is a moparts member who sells them with the vintage style cover.
Autozone has them with a short cad plated cover but it be modified to look stock.

ebay also sells them.
