A CS 144 would probably be enough, but the AD 244 will power the neighborhood. You will have to upgrade your wiring if you haven't already and use a separate junction.
The AD 244 will be a larger in circumference but it will bolt in place.
If you can put an amp meter in series with the negative battery cable and the post, then turn on the key and one by one turn on the loads with the engine off. Add up the amps each draws and that will tell you what your total draw is then figure 50% of that and that should be the size of the alternator you need.
For your fans and air you can take the fuse size and reduce it by 20% for the draw. Most fans will draw about 15 amps and the air will be slightly less. It should be labeled on the compressor or the instructions for vintage air.
I'll post a link that tells the size of the alternator depending on the loads if I can find it.
