Shimano Deore DX headset missing seal

[flame]

Hello all,

I bought an NOS/NIB Deore DX 1 1/8" headset but box only contained one of two seals. Having a hard time finding one online. Any leads much appreciated

Now that's from late 89s, so the modern part code would have changed, but only with some letters added.
Anyway, same as the XT version if you are looking, and yes it's the 1 1/8" version as is says so on the box.
Maybe someone has one from an old knackered headset.
