All you can do is look for a machine that is being parted out. You can buy a new one from Bobcat, but i can imagine it won't be cheap. You do know you can replace the pins that the levers mount to rite? They are simply a piece of round steel with a hole drilled and tapped that is welded to the bobtach. A spring goes between the bobtach and the back of the lever. If you grind the weld off you should be able to knock the old pins out and replace them. You just need to know someone with a lathe to make the pins for you. The other wear you speak of can be repaired too. You can cut the section thats worn out and weld in a new plate, but make sure you weld it well!! You can weld up the part where the bucket gets held with the pins, you get wear on the face but if you put a new plate or fill with weld you can remove a LOT of play.
Its all up to you though, i have done this before and it worked a treat.
