Where can i find repro Crown zipper for my A-2 jacket?

Hi everyone,
my current zipper is broken, so i need new Repro crown Zipper to replace it.
I didn't find it on greedbay, you guys got experience and maybe know, where can i find it.

PS: Eastman Leather reproduced the crown Zipper, can i take a Chance from Gary?

Thanks for suggestions!

Regards
Lee
