Maybe this will help. The front nut is removable but doubt you can get a new one but maybe you can either drill out the bolt ot fab a new nut.

Much thnx! Do you know where I can get the bushing?

I am assuming it would be a dealer item but most likely discontinued. You can possibly have one fabricated. Doesn't have to be exactly the same just so the nut doesn't rotate.
