remove the two bolts one from the top and the second from underneath and disconnect the cables (one held on by a nut in a plastic casing) which are assessable from beneath disconnect the AC line held by brackets with two small bolts on the steering rack and and gently push to one side, also undo the two 17mm bolts that hold the exhaust flanges together remove the rubber grommets and push the exhaust out of the way and only then will you be able to drop the alternator thru this tight space.
