Hi Paul, yup it's a snug fit into the garage. I also have a Volvo in our shop, a (V-90).
Your truck appears to be a 1957, but great to see the large backlite.
Have you considered replacing the complete floor and running board asy.to eliminate the swiss cheese holes. The rest of your truck looks quite sound. My running boards are thin and a complete floor may be the way to go.It will test my welding skills.
Great looking Chevy. Howie
