This stainless bracket is for mounting a CB antenna to the back of your sleeper. It mounts in the center 3 holes where the roof cap meets the back wall. Antenna Adaptor is not included. This is just a raw stainless bracket. It may fit day cab Pete's or other class 8 trucks. We designed this bracket to mount the CB antenna in the upper center holes of the bunk. Huck rivets will need to be drilled out and replaced with either new hucks or stainless bolts and nuts. Again, this listing is for the bracket only. The CB antenna Adaptor is only for display.
