The airbags and steering wheels that I have listed, as far as my experience, are all interchangeable(you will have to wire up the airbag). Also know that the Miata and Protégé will require slight modification. Read on…
Installation:
A GREAT reference for this is

1. Buy a new wheel and airbag
2. Disconnect the battery.
3. Remove the three rubber plugs on the rear of the steering wheel and remove the 3 10mm bolts that hold the Air Bag in. Use common sense, if you can’t get to one of the bolts, turn the wheel where that bolt is facing the 6 o’clock position(Just make sure you turn it back straight when you are finished) You can see 2 of the 3 holes in the picture below, one is to the left of the GFDO1 stamp just for your reference:

4. Slowly pull the airbag away from the wheel to expose the connectors. Disconnect the connectors. The Large Blue one is the airbag intermixed with the cruise control. The orange connector is the horn.
5. Make SURE that the wheel is perfectly straight when you remove it. This will ensure that the new wheel is put on perfectly straight. Remove the large nut in the center of the wheel. Make sure you have a long enough extension for you socket that it does not scratch the wheel as you are loosening it. In order to remove the steering wheel, I use an actual steering wheel removal tool that can be purchased at pretty much any parts store. It is pretty self explanatory how to use so I won’t go into details. Some have had success simply wiggling the wheel from side to side and pulling it away as well. Here is a pic of what the tool looks like that I use:

6. Now, the old wheel is out. Time to prep the new wheel for installation. In order to do so, you will need to drill two holes for the clock springs. You can reference the size of hole you need to drill by placing your drill bit in the holes of the stock FD wheel and getting a snug fit. Here is what the stock FD holes look like:
