When I bought my '70 SS396 Chevelle, it had "Hurst Equipped" diecast/chrome/painted emblems on the forward part of the doors similar but different than the famed Hurst Olds emblems. It has a Hurst 4 speed shifter. Was this a factory option? I have never seen these on any other car.

They put Hurst Equipped Emblems on some GTOs, you can buy the emblems aftermarket. I think Year One sells the emblems.
