964 piston measurement spec?

OK guys, I can't find this info from in my printed in 1991 manuals and my friends with 964 spec books say it isn't in their spec books (printed in '93).

My factory manual says the 964 piston diameter should be measured 15mm from the bottom of the skirt. When I compared a 1990 piston to a later style (cylinder has sealing ring on top) I found that the skirt on the later style is longer.

For a later style 964 piston, how far up from the bottom should the piston diameter be measured?


EDIT: It turns out that I have 993 pistons not 964 ones. Sooo... what I really need is the measurement spec for 993 pistons. Anyone have a 993 spec book?
