This is what you're looking for. These are from Mooneyes, but other comapnies that sell hotrod parts have similar headlamps. The fit right into the existing buckets, no alterations. I have see them with a separate socket for a park/daytimg running lamp that is not part of the lens like some of the others with built-in parklamps. I don't recall who had them, though.
BTW, I have them in
the '55, with the bulbs upgraded to H4 Silverstars.
