I agree 100% with using a chevy pattern front on your balancer. One issue it creates with some of the drives it attachment due to the size of the bolt and the way the balancer sits in a BB Mopar. We modified my Peterson to work with a stock bolt and washer set up. Or they sell spacers to go between the hub of the spline drive and balancer. We did not like the way the spacer looked so just modify the spline drive hub to work with no spacer
