Long Shot-Looking for tools to remove prechamber on 90 up Mercedes Diesel?

I have to remove the Injector prechambers on a 91 mercedes 350 SDL 3.5l turbo diesel. there are special tools to unscrew the top portion, and a slide hammer to remove the prechamber itself.

I know it’s a long shot, but I’d thought I’d check to see if anyone had something I could borrow for an afternoon?
it looks like this…
