I got a Professional Products SFI approved balancer when my stocker started coming apart. I got a deal on it ($90) because TMD on ebay sent me a fluiddyne type balancer for the earlier Fox mustang instead of the one I ordered. They don't work on our 94-95 stangs. I like the one I have now. Should be less than the romac if you are on a budget. And, do you really want to try and rebuild the crappy stocker unit?
