Body and Interior Specific Aid

Hey Kent, Are the 420 block and the 560 block about the same size? I found a valve cover thats off a 560 that will fit my 420. Are the block and heads the same, just the stroke is different.I am going to pick and pull tomorrow for the valve cover and safety belts. Should I just grab the engine and use some parts for my 420 or even put the 560 inplace of the 420?

Hi, I have a 1982 300TD. I am experiencing some strange instrument cluster behavior and I'm wondering if someone might chime in on how to fix it. I've removed the cluster a few times to make sure that all connections are sound and as far as I can tell, they are. Quite randomly, the fuel gauge and the temperature gauge start to jump a bit. If I switch the headlights on, the fuel and temperature needles get more jumpy, the buzzer goes on and off and the instrument cluster light turns off. The pressure gauge and others work as expected though I have to use a flashlight to see it. Thanks!

This morning I got in the my 190e and the radio was on, started OK, thought battery might be dead. Then turned on wipers, soon after smelled burning rubber, thought it might be coming from a construction site, only to find I could not turn off my wipers at the control stick-they are still on. It will not rotate, high beams work fine on and off, so do turn signals. So I have an electrical problem, I'll remove the cover to access the wiper, turn switch, no doubt, I'll see some major melt down there. Has anyone else had electrical problems with their 190e. I've just been driving this one for a week, I purchased it from a dealer with 97K. Where else should I be looking for problems that perhaps resulted in this issue I have this morning?

My '84 380sl came out of California and has pre-catylitic converters. If not using the smog pump, is there any reason to have pre-cats when replacing the main cat?
