Sorry. I had to get off line before as severe weather was moving in. I will get you the measurements. For the Motorhome I will remove the reflector pan and drill four small holes in the light molding frame and attach the led to the rear of the frame centered in the opening. then re-install the original red lens. The led cluster is small enough that it does not interfere with the red lens mounting holes but the circle is identical with the circle on the original lens. The lens that comes with the light cannot be used as the Airstream lens is curved and it is not. It looks like a very good match and when I applied 12 v. to it, it really lit up and when I applied voltage to the brake/turn lead, it REALLY lit up. Glencoombe, it looks like this is what we wanted.
