$330 for a CMP? Wow! I dont think there is any way it should cost that much unless you are buying the whole synchronizer assembly. The synchronizer is the piece that looks like an old distributor. The CMP has 2 screws that attach it to the synchronizer. If you remove the snychronizer you'll need a special tool to install it correctly. You should be able to replace just the CMP without removing the synchronizer.
