SNIP Just as a clarification, you are saying that the part numbers are the same for both manual flywheels and it does not matter which balancer they are paired with as long as they are both from the same CID (304, in this case). THanks again and have a great week, SNIP Jesse As best as I know, the short answer is as follows. As long as the flywheel or flex plate and harmonic balancer (3 or 4 hole) is off of the same displacement engine as far as I know you can mix and match as needed with out worry of affecting the balance of your engine.
