Harmonic balancer help

Yeah, thats the old CAT fluid damper, Version 1.0. I had that one to at one time and ended up just shimming both other pulleys, alt and water pump. I think I took the alt pulley off and pressed it on backwards to line up the belt and used a few washers behind the water pump pulley. Nothing major. There newer "2.0" had a recessed pulley face to align the belts with no mods. Guys knock CAT, but these dampers looked pretty good to me. Built like tanks.
