Looking for the way of old school

The real 68 Hemi cars had deleted window regulators from the factory. All they had was a seat belt type strap that pulled the window up and snapped or fastened to the inside of the door. Did those cars even have door panels?
They had the small bucket seats out of the vans and no rear seating. The odd thing was, all the 68 Hemi Darts I seen, had carpeting.
