I am in the middle of replacing my 1995 E320 head and thought that I had the correct 12 point 'socket', which is not really a socket, from Autozone but found out that I do not. I have read that people have seen them at Autozone but my local had no idea what I was talking about.

Is there any chance that there is a local place for me to get this incredibly important tool? I read one thread where the 12 point broke as he was using it to tighten the head down and really wrecked his day with shrapnel flying all over the place. I'll even go to the local Mercedes place if I have to.

Thanks very much,
Jim Lee
