Spanish F1s

I am hoping some of you will be able to help me!

I am trying to gather as much information as possible on the fleet of Spanish Mirage F1. Recent upgrades, amount of airframes presently in use and which aircraft are scheduled to replace it (Although I imagine that would be the Typhoon) is the type of info I am looking for. But anything else you could bring would be of great value. Cheers to all!
