Hi, i have tried searching about for a straight answer but cannot seem to find one on this, I have a multi-belt setup bottom pulley which i am guessing are for one side power steering and the other alternator. I want to keep the pas for the corsa c20xe. I have the bracket you get for mounting the pump but do i use the original pas pump from the corsa or do i need one of a cavalier,calibra etc? also the alternator do i just use the same one from the corsa and change the pulley on it or do i need to get one from the 2.0l to fit? any help would be much appreciated on this and if any has any links for what belts i need to get that would also be a great help, Cheers!
