In either case, the pulleys are bolted to the balancer, they're not part of the balancer. You should be running an 8 inch balancer (I"d get a new one) and you can bolt the pulley from the 81 on there if you're going to run the accessories from the 81.

The only difference that might exist is between the TDC locations on the two balancers - compare the keyway to the TDC location and buy the balancer for the engine you're using.
