Mercedes does not carry the speaker vinyl speaker cover any longer. So my next step is to try and repair. How do I remove the cover? it appears that it may snap in and out, but I don't want to force it and break something.

1975 300D Post Valve Adjustment Pinging OK?
I adjusted my valves for the first time a few weekends ago. Two exhaust and one intake needed adjustment. Engine runs better but it seems to ping more when it's cold. Is this normal and/or OK. I certain that I did the adjustment correctly. Thanks.

1982 300SD W-126 injection timing
I/P timing seems to wonder when checking. Car ran fine but in the quest to make sure my timing is set to 24 BTDC I noticed that it was moving around. I thought timing chain stretch so bought the kit, installed and I/P timing still moves from between BTDC to ATDC. I'm not able to get it even close to the correct timing spot. Help!!

83 300D Low MPG
MPG
Finally got a chance to make an extended highway trip on my new (for me) '83 300D. This is a one-owner car with a verified 116k miles. Drove 323 miles on I-75 on cruise control for 80% of the time at 2800 rpm for an indicated 65 mph. I drove about 30 miles on city streets and the rest on cruise control at 3,000 rpm. My mpg was 24.33. The mpg seems low. EPA says 30. I wonder if new injectors are called for? Or should I look elsewhere?

1975 300D Smoother Transmission after valve adjustment
I successfully adjusted the valves on my 1975 300D using the kit from MercedesSource (awesome wrenches by the way). Only 2 exhaust and 1 intake needed to be adjusted but engine does run smoother. In addition, my transmission is shifting much smoother, almost too smooth, almost like it is slipping but not quite.
Should this be a concern I don't want to pre-maturely wear out my transmission.

1985 300SD While in D will not go into N, R, or P somtimes
Over 200,000 miles, transmission never overhauled. I can always go from Park to Reverse and then to Drive. But sometimes while in Drive with my foot on the brake, I cannot get the shifter to go into Neutral to get to Reverse or Park. I move the shifter around but to no avail. This situations happens infrequently.
Another observation, when the shifting appears to be working, when I put it in Reveres, the whole body feels like it drops. And when I put the car in Drive it feels like it raises up. Normal/not normal, I don't know?
