I even called a few shops in Vegas that sell lots of information like that, and even they didn't have old sheets (was convinced the one historical shop would have them but they didn't keep them for some reason) I found some things on EBay, but only maybe one SB from years back. I, would still, like this information for a Super Bowl study. If you happen to look elsewhere, then PM me and maybe we can both search and help each other.
I did end up finding one web site that I got like 3 SB's from as well. Just not 20 years back, and not even for the game I was looking for in specific either. If you do enough looking around and use different search engines too, you might fall into something.
