I just bought a 65' Scout 80 as a project. I have all of the emblems for the most part, except for one. I cannot figure out what goes on the top left back, in the back of the removable top.
Yup. Indeed that is a hole for a cb antenna. The 3 tiny holes around the one big one is for the screws to hold the mounting bracket. And the big hole is where the cable goes through to hook upto the antenna.
