I was sure I had read something about this in some of my manuals. 
This is a quote from the Kenneth Ball manual:

"Reassembly:

Check that al the parts are clean and undamaged. Check for balance 
marks. Crankshafts are marked with a spot of paint on the end face, 
flywheels with a small hole drilled in the clutch face,  and the 
flywheel pressure plate with a paint line on the outer edge. If all 
three marks are present they shoud be assembled so that the marks are 
120 deg. apart but if only two marks are present the parts should be 
assembled so that the marks are 180 deg. apart."

I've seen the paint marks a few times, but I'm never sure which 
"small hole" in the flywheel they're referring to. Maybe it will be 
clearer if I look at a flywheel again now that I've re-read this 
passage.

Whenever I disassemble an an engine, I try to mark the parts so I can 
put them back together the same way, especially if I think there is 
any chance that the engine is a "virgin." By now, however, it's 
likely that most of our engines have been reassembled randomly at 
least once.

Do you happen to know if anything similar was done with torque 
converters and AT drive plates?
