I have just purchased a pristine '87 560SL. The light in the right (tach/clock) pod doesn't work. How can I replace it? I know the cluster will come out the front, but it looks like the steering wheel is in the way. Can I remove the wheel w/o fear of deploying the air bag? Is it possible to change the lamp by removing the stereo and reaching through the opening? I will be changing out the stereo very soon.
