If the crank is for an externally balanced engine (such as a big block Chevy), the balancing will be done with the flywheel and damper installed. As far as harness, i forget which year went to external crank sensor at the balancer but in 1989, it did not have this. The crack can be external meaning coolant or oils can leak outside of the engine. Other than that, the dampers are identical for each style engine except for 80001 and 90001.
