The stacked gauges were an option on the 69 Trans Am like any other Firebird and were not standard. The hood tach wasn't an option on the T/A, so if you wanted a tachometer you had to get the stacked gauges, which is why there were a lot of them that had them.
I have a set of stacked gauges that came out of a 69 350 2 barrel 4-speed car. It was a rusted out car that was crushed and the guy pulled a lot of parts from it. I wish I had bought the console and 8-track from him years ago, but the gauges set me back too much to afford it at the time.
On an unrelated note, I'd like to get these gauges restored. Has anyone had a set restored? If so, who did them and what did you think of the quality?
