is the arm of MLB that you want to contact to inquire about the availability. It doesn't appear they have anything to sell from that era, but they might be able to tell you whether anything has been produced that may show up on ESPN Classic someday.
Actually, you might have the best shot of finding something in an episode of "This Week in Baseball," especially if he had a play of the week or a blooper. I think Classic airs those once or twice a week year-round, at odd hours. If you have a DVR, you might set it to start recording them. I know I've seen an episode from '85 in the last few months.
