Looking for advice on A/C

My knee knocker ate belts within a week when properly charged, because the condenser was too small to get the job done with 134. Put in larger condenser, and bought a belt at Grainger with a much larger cross section. It rides about 1/8 inch up above the pulley edges, which has been no problem. I think the unit was from Western Auto, and it has a pulley the bolts onto the existing pulleys, but also has bracket that steps out the power steering pump in order to let the new pulley run the power steering, and the compressor belt runs in one of the original pulleys.
