Devin bodies came in 26 different sizes, including some for 94 inch wheelbase that would fit MGA. The Devin has been so popular for use as a racing car body that people may have the impression that the Devin was an actual production car, like the Elva Courier. There were a few "production" cars built as turn-key deliveries, but there were far bore bare bodies produced for custom builds.
