I have a friend with a 66 Shelby non-Hertz (believe it's in the high 700's but not 100% sure). There was a hole cut in his metal dash and the below guage was installed. I told him I have never seen one and he asked could it have been a supercharged car and that gauge was either added by Shelby or aftermarket for that. Since I have no idea I figured I'd ask:
1) Has anyone seen a similar gauge installed in the metal face of the dash? What for?
2) Does anyone recognize the gauge and what it may have been used for (if not a supercharger gauge)?
I hate to tell him it's not as sold to the first owner and have him close it off if it was something factory or dealer installed. I believe the car has been off the road since the early 70's.
