I have a 1998 Mercedes Benz E 320 and I had an ignition problem. Basically the key wouldn't turn when in the ignition. I ended up buying an ECM, steering wheel lock, ignition and a key. I swapped over everything, but now i can't pot the steering column together because i drilled my steering wheel lock screw out as it didn't want to come out. So the screw is destroyed and I need to buy new one. I went to a Mercedes Benz dealer and they sold me the wrong size screw that doesn't fit my car. They ordered by checking my vin #, but I'm not sure if I'm having this problem because I'm replacing the ignition, ecm, key and steering wheel lock with used ones from another mb. Can someone please help me and tell me where i can order this screw from.
