Anything is possible Graham. My understanding from Simon is the main bush is bonded to the wishbones and has to be removed and then a new one bonded back in, I presume if you can find a right size polybush then that could be fitted (not sure if they are not already poly). I presume there are bushed each side of the wishbone that it swings on, but I am wondering if these are some sort of rose joint arrangement, I'll see if I can take a look.
