Which Perko stern light replacement?

[FarmallM51]

I have a 1986 Tournament 19 and need a replacement stern light. GW says the original was Perko 5881, but that one does not seem to be available. The aftermarket replacements that I've tried flop around in the socket and don't always make proper contact. Does anyone know which of the modern Perko replacements fit the older socket, including the locking sleeve? Thanks.

Did you try contacting Perko, directly? It seems like going to the 'source' would be the most productive course of action. You may have to replace the base, too.
