Only cars Post 1999 with a ‘Euro 1 <6’ engine rating can get a Crit Aire certificate. The site is available in English (as well as other languages) which explains which cars qualify https://www.certificat-air.gouv.fr/en/ in the FAQ section.
If you want to drive your Traction in Paris I believe you can do so, but only on a Sunday. However don’t take this as gospel…..
