Thanks for the input guys. I ended up putting a copper sleeve over the dowels, securing them with epoxy and making sure the receiving holes on the fuse were snug with the sleeves. I also put some saddle tape on to snug the wing. The trailing edge of the wing sits about 1/8 in above the saddle allowing the bolts to pull the wing firmly against the saddle. The sad thing was that I really didn't have to open the holes in the fuse much to fit the larger dowel/sleeve. Thanks again, hope this cures the problem.
