Still was not happy with one of the pulley alignments (the ride side happened to be more tricky than expected). Took the pulley off again, tried to adjust the angle of the main plate even better. Unfortunately I had to remake the upper RH pulley attachment because the angle of the plate changed also!! Looks like I'm remaining at the same spot for the time being but there is just no room for flexibility.
That's it regarding the Alignments of the right Pulley
