What frame willfit a 1940 Chevy two door sedan?

A 1940 Chevy two-door sedan typically fits a frame designed specifically for that model, often referred to as the "A-body" frames from GM. If you're looking for a replacement or custom frame, options include aftermarket frames or those from similar vintage Chevy models, such as the 1939-1940 Chevy passenger cars. It's essential to ensure compatibility with the body mounts and suspension for proper fit and function.
