Voltage regulator conversion for generator cutout

[CBoz]

Hello - I have an oval-style generator cutout that I had converted to a hidden voltage regulator. Unfortunately I fried it and can't find the name of the person who did the conversion for me. Do any of you have any recommendations? I'm trying to keep the car as original looking as possible, otherwise I'd buy one of the round repro cutouts with the hidden voltage regulator.

Thanks in advance.
