Recently I was driving my 93 honda accord lx home from work and noticed a rattle from underneath the hood. When i got home and looked i noticed that I was missing the upper through bolt (pivot bolt) for my alternator. I was wondering if anyone knew what the specifications for this bolt are so I could stop this annoying rattle.

 

You might have to call a dealer ship, because the parts blowup for the 93 on hondapartsdeals.com doesn't show that pivot bolt. You can try to look around on the various pages to find it. A junkyard would be another good/cheap source for that bolt.

If you just noticed the sound, maybe you got lucky and it is still sitting on the splash shield below the radiator.
