Don't forget the water pump pulley, the Idler Pulley and a crank bolt.

The Crank pulley by itself will just sit on your bench unless you you opt for a new belt. (even then I'm not sure it would clear the WP Pulley)

The Crank bolt is $6.75 at the MB dealer (in stock) I doubt a Chrysler dealer would stock it.

Shawn posted a link to a 178 pulley on EBAY for $300. I asked the seller if he had the other pulleys - Nope.
