Rob, I don't know that this is what you're looking for, but my dad and my husband make frozen margaritas this way, and everyone seems to love them...although they may be a bit on the strong side! Sorry the measurements aren't more exact, but they always just use the limeade can! Hope this helps!

Frozen Margaritas

Place 1 small can frozen limeade concentrate in blender; fill can with tequila (Cuervo Gold) and add to blender; fill can half way with Triple Sec and add to blender. Fill blender to top with ice, and blend until smooth. Rim glasses with lime juice and dip in margarita salt. Garnish with lime slices.

By the way, I have made these for a party before and poured into large round coolers and kept in our freezer until time to serve. You just can't leave them out too long or they start to melt.

Have fun!
