[Cyanide] is an unknown quantity at this point
So I actually did just call the Colorado DMV Emissions phone number and spoke with a very nice gentleman and he said:

1.) OBD2 port testing is only required for 2005 and newer vehicles
2.) Anything older gets put on the dyno for the sniffer test

Hope this helps out someone!
