Where to source a half-link for an 8385-2 YG DD bracelet?

[TomWambsgans]

I'm trying to get my hands on a 32-20657 half-link (it may actually be a 1.5 link, not sure) for an 8385 bracelet. The local Rolex boutique called RSC NY and learned that these were recently discontinued. The boutique was nice enough to give me the part number, though.

I'm trying to find one to fix a minor fit issue with my 18238: It's either too tight, or juuuust a little too loose.

Anyone have any ideas where I might find one? I tried Googling, but didn't find anything. Any advice much appreciated.
