Wayne, the chrome frame around the gauges comes out with the gauge cluster. In other words the chrome frame is attached to the gauge cluster. On a 1940 Cadillac and Lasalle the outer glass in the gauge cluster is just a flat rectangular piece. Breakage is unlikely but a lot less critical than on a 1939 where the glass is convex and not reproduced. (very hard to find an original replacement). On both, the numbers are silk screened onto a flat second piece of glass inside the cluster. There used to be a vendor who sold reproduction glass with the numbers newly silkscreened on. That guy stopped doing that a few years back and I am not aware of anyone else doing it. I do know of a source for new radio glass with the numbers.
