79 300d striker bolt holes fell?
I was replacing the striker on my sons '79 and the bolts that the striker attach to fell. I can't see it and only the top one fell.. he was able to grab the bottom one with a paperclip and alot of patience. Is there are way to access inside that channel? Or another solution?

1984 300D aftermarket OE direct fit rotors
Thanks for answering my last question and all the other info I have gotten through MercedesSource by way of instructions and guides. I have new rotors that I aquired and the part number indicates that they go to the front of my 1984 300D. My question is that the old rotors (probably the originals)are bolted to the front bearing hub as you have confirmed. These new aftermarket rotors have no threads in the hub mating surface to accept the 5 mounting bolts that hold the old ones on. What gives? I have looked at other replacement brands also and see no way of fastening them to the hub.

1984 300D brake rotor removal
When removing a brake rotor, (disc), is it fastened to the hub with any clips or bolts or is it sandwiched between the wheel and hub then secured by the lug bolts? There is 25 years of dirt/rust holding it in place also so I didn't expect it to exactly fall off but I was wondering if there are any fasteners I should be aware of.
As always thanks for any info that is offered.
Great resource.......Mike G.

1984 300D rack dampner installation and adjustment
Hi all. I purchased the injector pump rack dampner bolt from Mercedessource complete with instructions. The mention of an O-ring made me somewhat prepared for some kind of fluid to be leaking out as O-rings are usually sealing something off. I expected diesel fuel but oil leaked out of the hole. There was no mention in the instructions of any fluids leaking out of the hole when removing the old one but I had some oil leak out and was wondering if that was normal.

1982 300D bypassing over-boost solenoid
I have researched quite a bit and everyone seems to explain the purpose of this solenoid but not elaborate on it. I can't make a standing decision if it should be left on the car or removed. On two of our cars, we have it bypassed. We just have the alda running to the banjo bolt. How does this affect performance? If the overboost solenoid cuts fuel down to N/A amounts, will bypassing it cut the fuel permanently? What does this do?

123 TD Wagon Rear Suspension Inspection Procedure ??
I own two wagons, an 82 and an 85. The 82 has rebuilt rear suspension in the form of new accumulators, shocks and leveling valve. The 85 has had the shocks replaced some time ago, but is now mushy and leaks down over a period of 12-24 hours. I'd like to perform a preventive maintenance inspection and performance test to determine the condition of the system and point to component failures. Where is a good place to start?

1982 300 TD Wagon - Removing SEM Vinyl Dye?
I just got my car back from the Upholstery shop. They were trying to do me a favor and dye the seats. The color they used is too light in my opinion. Does anyone know what I can use to remove the SEM aerosol vinyl dye without causing damage to the vinyl seats?

1984 300D Air...route of entry?
Hi all. Seems my car is pulling some air into the fuel system from somewhere. I can see tiny bubbles that gather in the clear pre-filter when I rev it up. She runs a little rough after a highway cruise too. I figured the leak must be somewhere before that filter. I have installed a new screen in the fuel tank and a new hose and clamp from the tank screen to the metal fuel line that leads to the engine compartment. Also purchased the fuel line kit and have new hoses and clamps on pre-filter in and out. All clamps are tight. My question is....
