I just answered my own question. Montalban played Cochise in The 20th Century Hour TV series (a series of single one-hour TV made versions of 20th Century Fox movies). This still starred John Lupton as Tom Jeffords. They apparently made the series after this, except with Michael Ansara. I found this by checking the last TV entry on IMDB for Ricardo Montalban under TV episodes. I personally never remember seeing The 20th Century Hour.
