Cross at Nogales and take the truck route. Easy-peasy. Then drive the 14 miles to the Customs and Immigration office.
If speed to Oaxaca or Guanajuato is your desire I agree with Scott's advise as well, but try to visit Edmundo and stay for at least for one meal in Los Mochis. The goat birria for breakfast or the ceviche guy are definitely worth a stop... You can drive from Nogales to Los Mochis in 10 hours or so.
BTW that is one purdy Cruiser...
