The test shot and box art for this kit are shown at the 20 second mark on The Scale Model Experiment you tube channel . See the video titled “fourth annual plastic in the park model car contest and gathering” posted on Oct 9/22.
If it is any help, 4 of the 12 tires in AMT’s 1962 Pontiac Polyglas Gasser II kit are white-lettered big and little polyglas tires. (There are also 4 stock and 4 red pinstripe tires).
I don’t have any suggested changes but I did want to mention that this book, along with your muscle car model kit one, are awesome and highly recommended.
