Does anyone know the bolt size that fits in the grooves to mount the spoiler? Thanks.

 

I couldn't tell you exactly, but I would recommend just taking it to Home Depot, or any hardware store, and just testing out different options to see what fits. Kaminari flush mount is awesome by the way. Throw up some pictures when it's done!

 

Your talking about THIS Kaminari Wing



Love to know how you or anyone else were able to fasten the 2 outer bolts to the rear hatch. If you haven't drilled the deck yet you'll see.
