My Haronic Balancer has a small crack

You got that right. They sure are. There's an Australian company makin some that are affordable. They're on Ebay. Both SFI and not. Even the non SFI ones are good quality.

?? i saw the romeo ones and they were like 300 bucks... you have a link?

also dont forget that slants have the same snout as a 440 crank
