I installed my APR GTC 300 on my Evo X SSS today, and in the bolt pack (bought off amazon as the wing was used and did not come with the mounting hardware), and I can't for the life of me figure out what bolt goes on the inner portion of the wing's base.

On the stock wing, it was under the plastic cover that had to be removed, but I'm not sure that the stock bolt will fit through the base since it's extremely short.

Is there a part number or bolt from a hardware store that will fit the same spot?

Thanks, UxC

 

It's the same tread pitch as the 10mm bolt that the stock wing uses.
