Gmt 16760 doubts oyster and jubilee

[Rafabond]

I am going to express a doubt that I have, I will explain myself as best as possible.

1 chapter

I have a gmt 16760 with oyster 78360 bracelet and endlink 501.
también tengo un Datejust 16220 con brazalete jubilee 62510H con endlink 555 B.

My idea is to exchange the bracelets, obviously neither of the two endlinks are compatible

To set the jubilee to GMT you would need a 502 B endlink.

and to attach the oyster to the Datejust I need the 558 B endlink.

Here comes my question, I have no price problems finding the endlink 558 B, but I do have a problem with the 502 B, I found some on chrono24 and they are crazy priced.

para que encaje perfectamente el jubilee al GmT ¿hay otra alternativa al endlink 502 B?
