273 questions...a few of them

Sounds like one balancer is for an early motor with the timing marks on the passenger side of the timing cover, and the other is for a later motor with the timing marks on the drivers side of the timing cover. You will have to put the motor at TDC #1 compression and see which balancer lines up with your timing cover.

Steve...you have to use the late balancer with the late timing cover, and early with the early, otherwise your timing light (and TDC) indication will be way off.
