no idea who did the machining,presumed they did it in house not farmed it out!
paid them £100 note for the privilage of getting the job done right,not slagging them off in any way top guys know there stuff & upmost help full!
when pistons arrived they appeared to "unmachined" apart from a tiny raised nipple in the centre of each one,quick phone to the just to check that they had been worked on & was assured that was the case
