Don't worry, these are indentical to the '69-'72 base model 1/2 ton C 10 cap, except the bow tie would be blue instead of gold. They are both steel. Chrome versions were optional '69-'72 and some '73's. Stainless was used generally from '73-'75. The flat type ( completely different style-but still fits) you mention must be the '76-'87 aluminum cap. Was the optional cap in '76 '77 '78, became the standard base model C 10 cap '79-'87 and up to the 90's on vans. All these 1/2 tons measure approx. 10 1/4 across, all 3/4+ 1 tons are taller and wider measure approx. 12" across.
