Marc,

The changing out of a standard 13B flywheel for a automatic 20B flex plate
and counterweight makes sense IF the counterweights from a 13B are identical
to the ones on a 20B.

Anyone know if they are the same?  (I doubt it, it would be to good to be
true!)

Thanks for your input.

Bob Darrah

As I understand it Bob, counter weights are used with auto tx flex plates.

Flywheels, with built in counter weights, are used with manual tx cars. 
Flywheels are too heavy for airplanes.

If you have a flywheel you need to discard it and get the right counter weight 
and use any flex plate.

Flex plates appear to be in total balance as is.

The counter weights on a 20b and a 13B are different.

I hope this clears things up.
