Blue Headrest Pads
 

The cushion things that clip into the plastic head-rests. They're the sort-of tweedy fabric, as on GL and Tors I believe, but maybe others too. They're in good condition, came off a low mileage car a few years back but in the end I didn't need them because I found some which matched my upholstery. Open to any offers, they're only worth what someone will pay for them!
