I need the Historical FORWARD 3-5 Year P/E ratios (using 3-5 earnings
projections) for the S&P 500 for at least 10 years, downloadable or
copyable into Excel, as detailed as possible, monthly if possible. I
do not just want a link, I already have them, and they cost a lot of
money, I just want the data.

An example of the data would be: The 3-5 Year Forward P/E of the S&P
500 of 1994 would use earnings projections of 1994 through 1997-1999,
known only at the time of 1994.

I want to know the projections that where made in the past. I am not
interested in the historical trailing, or current P/E's of time.
