The gear linkage on my ST170 keeps popping off the gearbox, iv previously zip tied it but the rubber part that goes on the ball joint has worn too much to the point where it wont entertain a gear change without coming off at all.

Can I replace just this end peice (if so where can I get it as I cant find anything) or is it the whole linkage that comes a complete unit, can I get a brand new one as no where seems to have these other than second hand.

Any help would be much apreciated.
