'None built for retail sale' may be a better statement considering John Z's '67 L72 Engineering Test car w/ 'Special Order' tag as quote below from this past thread...

Removed the "Special Order" tag from the left side front fender reinforcement and put it in my rollaway just before I sold it, still have the tag - photo below. There may not have been any L-72 SS427's built on dealer order for retail sale, but there was at least one built for Engineering; I bought several sets of rear tires for it in the two years I owned it.
