Being a '78, I think you have a balljoint front end with disc brakes, rather than the older kingpin front end with drums.
If that's the case, count your lucky stars, because it's very similar to every import mini on this site- 720s, Yotas, Isuzus, etc. You should have plenty of room for a 6" diameter airbag with a standard import bracket kit.
I'm sorry I don't have any pictures for you, but search around the forums and there should be a wealth of information and photos for you to learn from!
