Stewart Warner guages

[lowlySS350]

I have three SW gauges identical to these in the dash of my 68 Nova SS. They are in the dash pad above the tunnel(in the middle of the dash). Anybody recognize them? I have only seen one similar setup, that was in a 69 Yenko Camaro I saw at an All-Camaro car show at a college near me. Someone told me because of the gauges my car might be a Harrell or similar. Unfortunately the engine in the car is not original(it is a '73 350) so i don't know of a way to verify where the car came from. The car is a 68 Nova SS with an M-20 4-speed and a 3.31:1 12-bolt w/ an Eaton posi. If anyone can shed some light on my car that would be wonderful. I can provide specifics like VIN if needed. Thank you.
