Original Super Stock HEMI Dart LO23

Hey. Dedicated pages to those s/s cars is a great idea. I had a very fast one years ago, although it wasn't a s/s. It was a '69 GTS bracket car.
What was the e.t.s of those cars as they were made from the Hurst facility?
I take it, the Dual Gate His and Hers shifter is original to the automatic ones? Curious to know. Thanks.
Yes, the Hurst dual gate is the original shifter that was used in these cars...
