I like that look also, but when I finish the interior of my '69 SS I expect to replace the Hurst lever and white ball with a bolt-on Muncie lever and factory-style black ball.
I've read (and contributed to several posts lately) on what mods most Chevy muscle car guys find acceptable on these beautiful cars. Personally I like what came out the factory door but often add a few performance and dress-up mods that were common in the 60's and 70's. Back in the day guys often added steering column tach and under dash gauges, Hurst shifters, headers, non-stock wheels and tires, aluminum intakes and Holley carbs, as well as tasteful chrome and aluminum under-hood accessories. In later years we added electronic distributors, disc brakes and and better steering/suspension pieces.
That said, we left the "in the weeds" look and gaudy wheels and paint to the 'rod and custom" guys.
