What clutch plate to use ?

[Petr Brezina]

Just a small update:
Have found somewhere on the net that flathead's new 10 inch plate should be 3/8inch thick, which equals cca 9.5mm, new linings should be cca 3.5mm thick.
Checked it on my 11´ clutch and I got 10mm overall thickness with cca 3.4-3.5mm lining thickness. It seems to be specs as new, but the rivet's heads are only 0.7mm bellow the lining surface at the minimum point - which is not too much I guess.
The question is if the 11´ plate doesn't use thicker linings (4mm) than 10´ plate? Any comments?
