Spoiler mounting
 

Can anyone tell me the hole size that is drilled in the tailgate for mounting the spoiler?

Story behind this: I bought an oem spoiler many months ago and during the mounting, one of the toggle thingys (screw goes through it to expand the toggle to securely mount the spoiler) broke and fell into the tailgate. I have since mounted that side with a large rivnut. It sorta holds. I can't go through auto car washes because it gets pulled up. So, I bought the smallest drywall toggle bolts from the hardware store but fear they may be too big. Just need the hole size.
Thanks,

The hole for the Elantra touring is 13/32 or .410 inch.
You can use toggle bolts, but make sure they are coated like zinc plated.Also coat the bare metal.
