I asked my brother-in-law how best for you to proceed. He said it wasn't an easy job for someone to take on, despite what the Haynes manual says.
He said that if you can get in with a long-handled ratchet (or put a length of tubing on a short one) and a short (2 inch) extension then you can probably loosen the bolts and free the alternator casing. Be careful not to drop the bolts under the engine though.
My brother-in-law is only in year 9, but I'm sure he knows his stuff. I'm a girl, so don't understand any of it. Someone once told me that you need a fairy liquid bottle to fill the oil up down the dipstick hole. The man in Halfords was crying.
