Looking for 575sci tensioner pulley
 

I have a bearing failing that has damaged the inside or the tensioner pulley on my 256 Weiand/Holley supercharger (excessive clearance)the part is obsolete through Mercury Racing. Any leads on it? I think I found one but they have it listed for $335 that seems excessive. Any help would be appreciated.

Found this real quick. See if they know where/how to get pulley too.
