Hello everyone I just bought a 1980 300D Mercedes it runs awesome but I have a few Questions about how to fix some of the stuff.
1. Radio does not work even tho there is power to it.
2. No Dash Lights at all.
3. Odometer/Speedometer does not work and the clock I really don't care about the clock. 
4. The biggest of them all is that they sealed the sunroof shut I am guessing because of leaks But I would like to get it fixed. How would I go about doing that?
5. it does have some minor rust but I can fix that as I go.
Any help you could give I would really appreciate it. My Kids would too as they have to listen to me sing in the car! Payback is what I call it.
