Not even rally gauges? a very plane jane TA? Is there such a thing?
Oh yes! In 69 they were advertising 'build it your way'. Many people went for just the exterior 'bling' and nothing else special. And then some wanted performance with no 'bling'. My uncle, that was a foreman at GM in the 60's, always ordered all the performance options without any 'bling' at all. He always had people lined up to buy his used cars.
