Anyone have or know where I can get a balancer? My motor's getting rebuilt by Cal Hartline and my old balancer is cracked and GM has discontinued it and there's no dealers showing one in inventory. The only one I can find is the BHJ balancer thru Johns Performance, but I'd rather see if I can find a factory one. Anyone have any comments on the BHJ? $400 seems high for a balancer but if it's the way to go or if it's the only way I'll just have to bite the bullet. Thanks, Jason
