Does anyone know if the WAIS-III can produce a GAI? If so, how? And is there table that I can use to find the confidence intervals like on the WISC-IV?

Using the following scores from the VCI and POI:

VCI Subtest Scores
Vocabulary - 18
Information - 17
Similarities - 17

POI Subtest Scores
Matrix Reasoning - 16
Block Design - 17
Picture Completion - 15

Would those be the correct subtests for calculating a GAI on the WAIS-III? What would it be?
