Sorry about that. Here is the manual for the Super Stick.

It doesn't specify what the wing bolts are in this manual, but I'm going to guess that they are the same. 1/4-20 bolts are a pretty standard size for wing bolts. If you're not sure take the fuselage to hardware store and find the bolt size that will thread into the wing bolt mounts.
