What PARTS did Hurst and Chrysler put in the Super Stock Barracuda & Dart not in other factory cars

Yeah. Actually the S/S "A100" seats are a bit narrower & have no welting along the seams. I got my upholstery from Legendary & did have to mention that. I was at a car show years ago where a well-known S/S 'cuda was on display. I mentioned these little quirks to the owner who said he never knew that. looking back, these cars really were the epitome of factory race car builds. I'd even say the newer package cars weren't engineered from factory pieces as well as these cars. Oh, I'd love to have a new DragPak Challenger but very little of it is "factory" so IMO it doesn't quite count.
