Hello I have a 1995 C220, and need to replace the lock tumbler. I'm having a bit of trouble figuring out if I need to remove the whole dashboard or just the instrument cluster? if I need to just remove the cluster is there an easy way to remove it with out removing the steering wheel (which is stationary). And if I need to remove the dashboard can someone tell me how to remove it I have it loose but cannot figure out how the back side is removed ( near the windshield)
