Detroit most definitely did not drop the Series 60 in 2004. It was listed as a standard option for the MCI D4505 as late as the 2009 model year. It was also the standard option for Prevost's X3-45 and H3-45.
Americanos is very confusing. This should explain Americanos better:

So basically, Americanos was oringally an independent Mexican operator. Greyhound formed SITA in 1997 to inaugurate Greyhound Mexico service. SITA was basically a subsidiary like BoltBus, except Spanish-speaking for Mexicans. SITA bought 49% of the original Americanos and various amounts of other international bus operators, then used the Americanos, Amigos, and Cruceros brand names to operate everything. It appears that at some point, SITA also "borrowed" some Greyhound DL3s (#6200-6205) for a new operation called Autobuses Lationos, running Chicago-Laredo. The operation failed and the DL3s were returned to Greyhound. Amigos died early on and SITA was apparently disbanded and renamed to Americanos, then merged with Cruceros.
Then all the ex-SITA routes and equipment were registered under Americanos but some of the coaches were still branded Cruceros.
In 2013, Americanos merged with Greyhound. So at some point, SITA must have purchased the remainder of Americanos.
Then there was a Mexican company called Golden State Lines based from Los Angeles that was independently-owned but contracted with Greyhound for maintenance and leased some equipment. The operation was shut down due to "trafficking" and police temporarily closed the Los Angeles terminal, causing massive disruptions to Greyhound and SITA operations.
Most of the SITA coaches were Viaggios, G4100s, and G4500s. They apparently also used 102D3s and 102DL3s for US domestic routes. At the border, the American coaches would be switched to a Mexican one like the Viaggio.
All this is extraordinarily confusing.
