Not necessarily but use the ribs and save the weight of the extra glass and resin. Using the ribs will help insure a true surface when sanding. As to the wing attach fitting bolts, there is probably a recommended torque value for that size bolt but good and tight seems to work for me. On the bolts through fittings to the spar, don't crush the wood. Larry Flesner
