Removal of alternators is easy if you know how! I've taken out loads. The trick is to get a track pin, cut off the threaded potion and slightly round off the edges. You can then insert it into the cap screws, tap it in with a hammer or mallet and turn it with a spanner. I got the process down to 10mins with this method, even with the engine in place. Yes the brackets are fitted to the alternator before it goes in.
