Steering coupling rubber - not available by itself from Ford. Whole couplings used to be available from Ford for about £90 - but no longer available.

GMS may be able to supply you with a rubber - you'll need to remove the coupling from the car, drill out the original "bolts" and replace with new rubber and nuts/bolts. They're on 0191 377 1718.

If they can't help, get yourself a 4x4 coupling, cut it shorter (in the middle of the coupling) and then get it welded up again . The added advantage of this is that the 4x4 couplings have a UJ on each end - no more rubber to perish.
