Didn all LS6 Chevelles have gauges and a tachometer?
No. The Instrument Panel Gauges, or Special Instrumentation, sold under RPO U14 was always an option regardless of year. The gauge pods for fuel, speedometer, and optional clock were round as opposed to the linear sweep speedometer of a non-SS optioned Chevelle but the gauge package, as well as a clock, was still an option. {Note: The same holds true for such options as bucket seats, console, and cowl induction hoods.
