Fabricated brackets. First screw-up! Need to re-make one of the pulley brackets as I did not pay attention to the flange direction and had it backwards. Set aside for now and order aluminum flange when needed. P/N 602-04101-3. 6061-T6, .063 x 7/8�� 1/2��Might be able to make locally. Only need one more bracket...3��ngth.
