UPDATE: The October 1962 issue of Four Wheeler Magazine included an ad for the Harris top and doors, along with an article.

This ad appeared in several Four Wheeler issues, including the June 1966 issue. I’d have to guess that by 1966, Harris had dropped its soft top product and focused on the dura-doors for jeeps.
