Began preliminary rough sanding of canopy fiberglass. Worked on seat belt crotch strap supports. Drilled passenger supports in place with a spacer to fit seat belts. Removed components and deburred. Primed components and installed platenuts. Bolted in crotch strap, clecoed assembly in place and pop riveted assembly in place. Fitted seat pan in place to make sure assembly would attach to seat pan. Fit OK. Worked pilot side supports in same manner and clecoed assembly in place ready for pop rivets.
