Can someone direct me to an online diagram that shows the various parts of the ignition key, cyl, housing, diesel shutoff valve, steering wheel lock, etc.

I have a car that is missing all these parts, and I need to figure out which ones to get.

Question: Which key system parts are the same for a W124 300E (gas) and the diesel car. 300E's can be found in my local Pick-n-Pull...but not so....for a diesel E300D.

If anyone has these parts from a diesel part out ...I'm a buyer.
