This was mounted on a cab-over Chevrolet, the roof of which has ribs, so they had to notch the base front & back. I'll sell the motor, as shown, or the entire partial assembly, which is minus base gasket & dome. Dome ring is shown as-is to show it exists - slightly bent at the clasp but still works & easily straightened. Can remove lens holders, rotating mechanism, whatever, if not wanted, but also have clear, red & a few amber sealed beams. Works great at 94 rpm. However you'd like to do it. Please email me at
