One trick you can try is to find the cert numbers of the other cards you have found, like in the APR page on PSA's website. Then with the cert number of a known card from the set, you can type in nearby numbers to see if it was submitted with other from the set at the same time. I remember cert numbers starting with 90,000,000 and ones around 11,000,000 from the couple I spotted last night. Once you've found those, you can figure out which year it was submitted by finding modern cards that were submitted around the same cert numbers. It's a little tedious, but there is a workaround.
