ok looking at the pic some more..
i think you have the a/c pulleys
you have the 1 alt belt straight down to the crank and the ps and wp run on a belt
you just need the front alt-a/c bracket to support the alt pivot bolt
that will line the belt up straight
look at the belt you have on the front groove of alt to the crank...see the rib on the neck of the wp that wont let you run another belt in the rear groove from alt to crank
thats the piece you want to remove and file flat and run 2 belts on the alt
other option is get non a/c pullys and alt brackets(like in all the pics posted) with correct belts and a single groove alt pully
the other thing to remember with the pully ratio is the a/c wp use the smaller pully and 6 vane wp
the non a/c pulleys use a larger pully and 8 vane pumps
not good to mix match the pully ratio and wp vane count either on high rpm engines,it can cavitate at the wp vanes.
