Looks like Indy. I see the Hurst banner where they would repair shifters at no cost. If you showed your participation number, you could buy shifters and parts at cost. How times have changed.
Must have been a Dealer leader or special order “Plain Jane”. Did Buick offer a Standard transmission in 58? If they did I bet this was one of them.
There comes a time in every person’s life when you contemplate your mortality. Looking back at what one accomplished. Did I do all I could with what I was gifted ? Did I make my parents proud ? OR did I waste my god given talents doing stupid things that I regret now ? We will all have the moment eventually.
