Well done with the fix. I've done a similar thing for now. As the headers are sturdy I've just built everything up after spraying it and even though I'm two nuts short, the joints don't appear to leak. I did a bit of a test run yesterday (after purchasing an essential bottle of milk) and it will be fine for now until I can get it fixed after lockdown.
I think the studs on the FZ6 are a bit easier to get at than on the FZS600 from what I remember; they are on shoulders and not directly into the main block of the head.
