There are different mounting plates for this particular alternator family.  The main thing is to identify that this is a 4G, by seeing the black metal back plate on the back of the alternator.  Our kits come with a Rotor with a slip ring already put on for you, a rear bearing, a front bearing, and a regulator.  There are two types of kits this could be the regular 4G or the 4GWB which only has a different regulator on it.
