Here one from one that was for sale. http://www.v8buick.com/index.php?threads/1970-gs-455-for-sale-numbers-matching.182489/
I had one that was a December build, Harvest Gold, Gold vinyl top and Burnished Saddle buckets. (The gold vinyl top option was dropped after December). Mine unfortunately was too far gone (engine fire forced original owner to sell it, I bought it but being a busy and broke college student I never finished it). Patrick
I've got a '70 Chevelle that's code 58. Chevy called it Autumn Gold, as each one had their own name for the exact same color.
I have harvest gold non vinyl top car with burnished saddle interior. Wish I had pictures but the car isn’t done yet.
