Yep dual pulley kit from RB or Mazdatrix and 2 identical fan belts will do the trick. Make sure
the belts are from the same mgfr, same lot# and same size. That way they will be closer to
being identical sizes and will stretch similar amount.

Once the pulley is on, tighten the belts down until about 1/2 inch deflection, run for a few
days or 100 miles or so and see if they need to be tightened a bit more. They will stretch.
Don't overtighten or you risk premature wear on the ehaft.
