I drilled and tapped the nose gear for two allen head bolts for the Towbar to grab. It works just fine. I also dug out the fiberglass and foam for five one inch hard points for the overhead panel. I cut the 1/4 inch by 1 inch aluminum bar into five 1 inch pieces, scuffed them up and glued them in place. I also installed two nutplates, one on each end of the overhead panel. Next time I will drill and tap the hard points and the overhead panel will be easily installed and removed for future maintenance.
