    Is there an easy way to convert the old Wilson si index(swing / stiffness index) to the widely accepted RDC ratings?

    You can try doing this yourself. Use racquetfinder.com to select all the Wilson racquets (uncheck the current models box.) In a spreadsheet, enter the RA and the SI. Do a scatter diagram and see if there is a linear correlation. I don't think the correlation is linear, but I could also be wrong. HTH.
