Ladymatic 134 end link compatibility?

I recently got a nice bargain on a reference 565.001 Ladymatic and would like to source an original bracelet for it. According to this thread, the watch took a 5405 bracelet, with no. 134 end links. I have a good lead on the bracelet, but the end links are proving a bit more scarce. I wanted to ask if there was potentially a different end link number I could search for that would also be compatible? For instance I know that no. 6 bracelets evolved into 516, no. 11 into 511, etc. and can be used interchangeably.

Alternatively, what are my other options for fitting this watch on an original bracelet if I can't find original end links?
