[QUOTE="timetraveller, post: 22133, member: 456"] Hi Gentlemen, perrhaps I can tag along here on the back of this thread. A year or so ago, when I was supplying the needle roller thrust race mod for the twin clutch push rods, five of you asked if I could do the same for the Comets. There was also an enquiry to see if I could do the same for the Honda clutch which some people are using. It is not possible for the Honda clutch as its design means that there is not enough free space inside the clutch to let the new parts fit. As I have no expertise with Comet clutch I was kindly lent five Burman outer aluminium pressure plates in order to help me to design the bits. The first was from Ian Savage at the Spares Company who lent me one with a 5/8" UNF thread in the centre to take an adjuster.
