An alternator adjuster hook? I need one for sure. However, the eyebolt worked perfectly and cost me only $5 and that only because I bought a stainless M10 bolt.

I want to take a picture of the alternator on my 6.2l detroit diesel and send it to Mercedes and tell them, "you want to know how to install an alternator? Look under the hood of pretty much any American truck, ever!" Mine even has a convenient hole in the bracket for the insertion of a pry bar for tensioning the belt. I guess the use of a pry bar is just too much for the feint-hearted MB engineers :-)
