PonyRider, this site is for you. Ford in the US have opened their 'Heritage Vault' to everyone. It has photos from their archives including brochures. The second link is a brochure of the '66 Mustang. Click on the picture on that page, not where it says 'Download'. It takes a while to download but is worth looking at even though it is in French. It would also print quite nicely. https://fordheritagevault.com/ https://fordheritagevault.com/scripts/mwimain.dll/144/DESCRIPTION_OPAC3/FORD_DETAIL?sessionsearch&exp=sisn%20271073
