Ed, Ive never met you, but you are funny and correct as hell. Every single time in my life Ive tried to save $10 it has cost me $50 to fix the problem I created.
OP, If you want to buy a new balancer, for a supercharged car, buy an Innovators West AND hopefully you have a double keyed crank AND make sure to attach the pulleys to the balancer with 8 ARP bolts not the 4 the pulleys are pre-drilled for.
