Ballast Resistor Fastener

[twenty mike mike]

What size and type fastener is used to mount the ballast resistor? I'm fairly sure it's not supposed to be a flat head wood screw.

I see what happened now. Someone installed a ballast resistor with the hole in the ceramic, instead of one with a mounting tab. Since the original bolt was too short, that went in the gutter and the nasty screw went into the firewall.

Thanks for the help.
