also depends on which dash package you have. The full digital panels use a different sending unit than the buttstuffog gauge.
The full digital senders are not available.

If you search the forums, you'll find multiple posts which basically say this:

There are several different sized tanks for our cars, and also a change in resistance for the fuel level senders. BE SURE you get the correct sender for your year/gauge/engine!

1983-86: 75 Ohms empty, 10 Ohms full
1987-88: 16 Ohms empty, 158 Ohms full

Then you can search through this page to find the sending unit that has the same readings as what you need:

Finally, when you get your mustang one, make sure you bend the bracket to match the bottom and top of your tank. 

If yours isn't a rusty piece of  like mine was, you can likely just clean and adjust your contacts (they are simple devices) and reinstall.  Again, instructions are on the board with a little search power.
