ace hardware. do you have the pic of them, or do i need to dig it up?
edit... nevermind, i found them.
ignore the bottom parts of the pics where it shows it with a nut on it. i was using the nut as a spacer (which you may need to do as well, depending on the length of the bolts they have).
this is the top half of the nut/bolt setup...
and this is the bottom half...
