replacement Z1R front fork bushing

Does anyone know of a replacement for these top bushing, never sold as a separate part but they do wear and l have a damaged one. thanks.

According to CMNSL the Z1R shares the same fork seals as all the below, on that basis a "kit is likely to do the trick" (not a guarantee)

I had this issue many years ago when I pulled the worn out bushes from my Z1Rs forks only to be told afterwards that they don't list them as a separate part when i went to the shop so i had to buy a good used set of forks from a breakers.
When they arrived the stanchions were an inch too short and it turned out they had sent Z650 legs.
However the sliders were the same K207 casting so while swapping them onto my Z1R tubes i noticed that the 650's bushes were retained with a circlip where the Z1Rs weren't.
A call to the local Kawa dealer confirmed that the Z650 bushes were available separately and after a quick comparison found out they are the same part so rebuilt my original Z1R sliders with new 650 bushes and got the breaker to take back the wrongly supplied 650 forks.
