There are actually three types of push buttons. 39's are longer than 40's that slide on with a snug fit. I believe the 41's were short, but needed the little spring clips inside of button to fit snug. Wine Red or Brown. 40-180 usually used the Wine Red which look better when lit than the plain brown ones that don't glow when radio is on.
