blower specific balancer

I just got a powerdyne and it doesn't have the balancer (I got it used), what's the difference in pulleys and can I modify the stock one?

If it's anything like a Vortech, the front of the balancer is machined flat to give the blower pulley a good surface to seat to.

That's what I was thinking...I'll figure out a way to make it work. Thanks.
