Where was i ranked 3 days ago?

Need to see "old" serps positions - is this possible?

[jasonlambert]

I recently made 2 SEO orientated changes to one of my websites; affecting about 60k of Google-indexed pages. Some of these pages have now been re-cached in the Google index.

Unfortunatly, I didnt record the rankings of any of the pages for certain keywords before I made the changes, but I now want to compare how they rank to their previous positions.

Anyone know if this is possible or not?

ie, viewing "old" (less than 7 days old) serps results for certain phrases?
