In '63 the Valiant (maybe other MoPars too) used a torsion bar system to hold the trunk open. The bars ran horizontally just below the rear windo package shelf and took up almost no space. They never had to be replaced, always worked right. I can't understand why simple mechanical systems that work are replaced with stuff that wears out.
If Chrysler would look back at some of the features of their cars of the past, they'd find a lot of good ones that they could bring back.
1st gens have this system
