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

all side glass was thin light weight
front bumper was acid dipped
fiberglass front fender
fiber glass Hemi hood

Good thread davescuda. Lets leave no question mark left when we are done :)
I believe front bumper was stamped thin steel. Same gauge as body panel... Someone?
Speaking of rear end. Leaf springs, front hangers and rear shackles were special for these cars.
