Mike ,Excellent info-sounds like an expert to me. How did special package trucks work.
If I walked into a dealership in 1976 and said
" 1 Dodge True Spirit please" it would come with the stripe package or ordered a Warlock -Stripes/Chrome step,wagon wheels..did True Spirits have specific wheels/decal colors?Could you order the True Spirit or Warlock package and upgrade anything from there,say window trim,bed cover,dual exhaust,side pipes,4 speed,Tuff wheel,Sure Grip,Painted in headlight surrounds(for '77/'78) etc....
