732000 was the first Bronco built for Shelby. Looks like yours was a late build. Hop on https://classicbroncos.com/forums/ if you haven't yet. They love seeing 66s
Just joined the site and thought some of you might like to see what it takes to restore a Classic Bronco. I have documented the entire process from buying the Bronco 8 years ago, to the tear down, restoration and now car shows/magazine shoots.
It is documented on the Classic Bronco site...
