Brief Description: Install seatbelt crotch strap parts
While admiring the assembly and looking over the plans I remembered a kit for the seatbelts. When I sifted through the boxes of parts I found it! The crotch strap kit. The plans don't mention this necessary addition. Glad I thought of it when I did. Mounted the parts and drilled the ribs.
Pored over the plans and just generally inspected for other details I might have missed. I think I'm ready to put rivets in and make things permanent.
