They were the guys that were selling the Bosch LP079 & LP032 Glow Plugs off at £4 a piece too, they were really really helpful over the phone when I rang up about my clutch, they even went to the hassle of checking a 2.7 aganist a 3.0 to make sure there were no more differences other than the diameter.
My car as far as the paperwork tells was on it's original clutch which when it went on 7th December 2016 had done about 156,000 miles there or there about.
I'll let you know in another 156,000 how it's doing although it may have a new engine by then, who knows how long mine will last before something terminally irreparable breaks
