AW11 rear toe link options

My rear toe links have the ball joint inner end. They both have play and the OEM part is no longer available. Has anyone been successful in rebuilding their link by pressing in a new bush? Is there a similar joint that can be made to work from an aftermarket or other parts bin?
 
Id love to hear from anyone who has done this before. If your in Vic and have hanged on to an old link, Id also like to get hold of a spare. That way I can see if it can be disassembled and rebuilt without taking my car off the road.
