Zastava M-57 Tokarev Recoil Spring Assembly

[Hondo 60]

As stated in the title, I'm looking for a Recoil Spring Assembly for a Zastava M57.
aka - Yugo Tokarev

There's a bushing on the muzzle end that holds the spring onto the guide rod.
That bushing is the part that broke.

I found only one site that had one
https://www.buymilsurp.com/recoil-spring-assembly-yugo-m57-762-pistol-p-42329.html

But of course, they're sold out.

Any assistance with finding one would be GREATLY appreciated.
