Well the tools I showed would have worked FINE if I hadn't dropped the GP when trying to install the NEW one in cyl #3!!!!
I was retarded and took over an hour just to find the damn thing. Turns out all I had to do was slide myself under the car to below the starter and voila it was right there.
My man Ron up at Crown Mercedes was right about needing "to be a contortion artist." Especially for GP#3, there is only 1 (ONE!!!!) way to get the socket extension and that swivel/pivot thing in there. Cyl #1 was Easy, #2 was semi-easy but tedious because I could only do baby increments of ratchet movements with-in the manifold opening. All of you manifold removers are probably laughing right now... but it is cold outside here and I do not feel up to dealing with undoing injector lines and what not JUST to do GPs... So ALL off this that I went through is that much less stuff to take apart and go wrong with the car. Next time I know where the fallen GPs will likely go to... THAT HUGE MAGNET OF A STARTER!!!
Good luck future GP replacers!
