There was a pressed steel bracket, that was held in place with two screws, that faced the inside of the cab, under the windshield weatherstrip , where the dash is spot welded to the cowl. There was also a rubber bumper attached to the speaker bracket that rests on the radio. The radio had a bracket that bolted to the cowl as well as the radio. The speaker magnet protruded through the bracket, the top of the speaker has a foam gasket that contacts underneath the dash where the speaker grill is visible.
