Just an FYI for you guys:

I received a used ATI "Super Damper" as part of a package deal. It fit the crank, but the there wasn't any water pump pulley. I sent them an email, and they actually called me back. They went ahead an custom made me a new hub carrier for the damper, which has the water pump pulley on the backside, (in between the front cover and damper). The one they made for me has a 4" pulley, but I beleive this can go either way.

Anyways, for anyone else who is interested, they should be listing this part in their inventory soon. The only catch is I beleive they go for about $500 complete
