I saw this mentioned too, David, but assumed that was a A/C compressor clutch being referred to: "Aircon pump, clutch and condenser fitted 79,966 11/09/2013"
"Ford racing Cobra Clutch" was at about 47K in 2008, so say.
How long do clutches last on a 260? No personal experience of course.Dependant on mileage a clutch change whilst it's out?
