Ah, someone put a serpentine system on it. Now it makes sense why you're stressing about mounting. What doesn't make sense is why you need something more than even a 100 amp alternator. The pulley diameter certainly doesn't look large enough to be under-driving it. All the stuff you list and the draw of all the stuff you didn't isn't going to draw anything that even a basic 65 amp alt wouldn't replenish. I'd make sure to clean up the wiring connections and the vehicle grounds. Then I'd do a test to see if there is a draw occurring when the car is off. Always a good idea to check this even when things seem to be good. Could be you just have a poor alternator and a new, better performing unit wouldn't hurt but don't waste your money on some super high output unit you don't need. My two cents, anyway.
