You know, I just opened that link in your other post. I had overlooked it before I posted mine. A guy from France already had the magic number back in 2006!

92 looks solid. Three people could be wrong but it's unlikely. Thanks for the link and the confirmation measurements. Now if I can just find a way to remember it.

I measured my clutch up last night. All Nissan parts from Courtesy (pressure plate, clutch disk, throwout bearing) purchasesd for a stock 240Z, with what I believe are the original 1973 transmission and collar...to the fork finger I measured as best I could at 95 mm. The finger does taper slightly and all is installed shfiting smooth. There were other issues which are best left unsaid...all good now.
