Searching for transom corner cap (deck cap)

[rivermiles]

Looking to replace a missing corner cap for transom for a 1974 Starcraft 21ft. Holliday. Need the starboard cap. Any leads on how to find one?

Ebay

But the last time I saw them there, they were urethane caps not aluminum

I'd probably try to find a metal fab shop and have them weld up a good approximation, or a pair and replace the other one 2.

I had to do similar for a 60s Larson, so the caps matched each other, even if they werent original
