Anybody here go to NBA Finals game 5 in 2001.?

I saw today that PSA graded game M tickets as from Game 5 of the NBA finals in 2001. I went with my son to that game and my tickets have a different game letter so I was wondering if anybody else here went to that game. Game 5 was the 13th home game that year, but the Sixers changed up some letters to help prevent fraud. And I have seen tickets not labled M sold on Ebay over the years as from game 5. My hope is that worthpoint has records of these sales dating back to when the tickets were sold to attend the game and the letter really mattered.
If not this series anybody else attend playoff games that were out of sequence for Basketball or Hockey?
This is why folks dispute many of the sites that claim to have cracked the code on non dated stubs mostly grandstand and bleacher stubs because no hard records were kept and weather travel problems etc. Could easily result in a year or many years being off by a digit or 2. Meaning the Ruth HR stubs etc. Are really just a hest guess. Educated and researched but in the end a best guess. Which is why I much prefer dated stubs.
