Hatterasguy,

A 27mm or 1 1/16 deep socket will work to remove the injectors. Either should be available from Sears. This socket also works on the crankshaft nut to turn the engine by hand.

BTW, the injectors on my 300SD have 250,000+ miles on them and I'm not about to repace them as long as the engine runs well with no knocks other than the norman idle rattle. GP also will be replaced as required, I.E. when they are dead.
