Long story short-On my1975 240D, I broke the plastic glow plug/start/stop knob, begin using vice grips, probably marred or bent shaft.

Step one fix-pulling it loose-won't happen. Two very stong men have tried.

What do I do next? I will do anything to keep "Old Blue" running as I have had her since new and she has more than 900,000 miles on her and never let me down, with the exception of the plastic knob...Please give me a fix I can do myself (I'm a 62 year old lady) or be able to tell my mechanic..Thanks!
