Decided on making a lock seamed bead to attach the airbox hood to the airbox. This
gives me the access to regularly check it and keep it clean and rustfree.
Here you can see the bead trial fitted to the hood edge
Here again the bead fitted, and a loose piece of material fitted to check the body fit side of the bead
Viewed from the inside edge of the hood
Viewed from the top of the hood outer edge.
Problem uploading a close up view of the bead, hopefully tomorrow
