Either way would work, but the most preffered method would be to use nylon bolts. Typically for this setup, you would install 2 wooden dowels into a beefed up leading edge that would fit into 2 holes in the fusleage at the front of the wing saddle. The rear of the wing would then be held in place with a couple of nylon bolts screwed into mounting blocks placed inside the fuselage. Regardless of your preffered method, I would use whatever the plans recommend using assuming that you have plans!
