While we're showing switches, have a look at this...
These are two different styles of switches. They are two gang switches, so not correct for an E body, but the style of the bottom one is like was used on the E bodies (and like others pictured in this thread), and I'm not sure when the top switch is from. Later I'd guess. Anyone know? (that's its NOS box next to it)
