Sorry it's been so long. Tracked down all the packaging from the pieces I replaced and here's the break-down

1.) Ignition switch- Plastic piece that clips in behind the steering lock and the wiring harness plugs into.
Mercedes Benz of West Chester sold me this for $34.50.
Part # A 202-545-01-04

2.) Tumbler (CHrysler calls it Cylinder Lock Ignition)- Simply put, the lock tumbler that you put your key into. Purchased from Jeff D'Ambrosio CPJ. Paid 138.00 (indusrty price through work) Normal retail 200.00
MB Part # A 202-462-00-79
MOPAR # 5101710-AA

3.) Steering Lock Assy. (Chrysler calls it Housing Ignition Switch) The bulk of the project, the tumbler spins inside this and the ignition switch screws in via 3 screws in the back. This piece goes into the steering column. This piece also included the ignition switch so I returned the one from MBZ of WC. Paid $81.90 (Industry price) Regular retail 130.00

Once again I do apologize for the delay, I do know how time critical this can be
