We bought to of these for out car a while back.They came from a car which was dismantled for spares.One of them went onto our BX,this is the other one. No longer have the car unfortunately so no point keeping it as a spare.
Its never been near a barn. The gaiter will need repairing or replacing. These are rarer then rocking horse pooh or honest tory politicians.
Happy to post it to you. Also have a diesel pump,starter motor and alternator.
