Update 3/1/96
After seeing this thread resurface again I checked my source for the fork end. I
comes from TR4 and from an older Victoria British catalog the part # is 4-740
(price $1.55) which was just the fork end (good on TR2-TR4) used with a hardware
store bolt and nut cost in the neighborhood of $2.00. Still
works today! See details above!

Just a note! All lost motion in my system has been eliminated clutch problem
fixed.
I also have new slave and clutch masters to put on this spring. I believe my
clutch woes began as a result of excessive crank end play. Need some advice on
thrust bearings. Please note my "Thrust bearing" post.
Good Luck
