Valiant convertibles were also built and sold in Mexico. The 65 Mexican Valiant Acalpulco convertibles and hardtops are especially cool since they're basicly the same as a US Valiant Signet but they were built with a 65 Barracuda grille.
Heres a link to a site with vintage cars for sale in Mexico http://www.autoclasico.com.mx/site/default.aspx From this link, go to "Autos en Venta" and enter "Valiant" for your search or "buscar" .
Most of the Canadian built Valiant convertibles used Dart bodies, though in 63 and 64 the Canadian Dart bodied Valiants had US Valiant front end sheet metal and grille.
