The alternator has 3 different length bolts holding it on, keep track which goes here because if you put a longer one where it isn't supposed to go, you'll send a bolt through the rear valve cover.
As for the bracket, there are 2 visible bolts and one that's hard to see that's closer towards the power steering pulley. Those 3 are the same length though.
As far as replacing the elbows, just pull them out of the alternator bracket....be sure to get them out completely because I have seen some leave a broken piece of plastic inside the bracket. Clean out the holes and install the new elbows with a little grease on the rubber o-rings, it helps them slide in easier.
I get the elbows at Pep Boy's help section......they sell them for $4 for both while the dealer chargers over double that.
