I want to get rid of this and hate to throw it on the junk pile.  Spins free, but I think there is some bearing noise, so I wouldn't use it as is.  Might be a good core for a rebuild for a spare. It came off of a B9 block, so it's probably a later version if there were versions.  It fits in a medium size USPS flat rate box, so shipping is about $13, so any good offer over $13.
