2003 Honda Accord 4cyl auto LX
 

I decided to check the air filter (pain in the neck) and got the
housing apart and cleaned it. However putting it back together I
dropped and lost the screw/bolt nearest the strut (you'd think this
would be the easiest almost but not for me). If I want to replace
it, does anyone know the size/length of the bolt and can it be had at
a auto parts store or is it a dealer item only?
