Tool Box

I found 4 Bondo filled holes in the rear fender. Earlier I had noticed what looked like a tool box behind the seat on pictures 3a, 4a and 5b. I decided to go ahead and purchase a 1950s vintage road flare box now that I have a better resolution picture of 5b. I am not certain this is the correct box but it is the closest thing I could find. I bolted it up to the existing holes. I wanted a tool box to carry tools and a spare #35 primary chain.
