funny thing is, I don't remember him fighting all that much, but I do remember a quote where someone asked him why he fights and he said "because it's there." - but at the same time he has no memorable bouts that I can think of.
dropyourgloves.com has him with 65 fights, so I was "sorta" right because it meant he only got into a fight about every 22 games.
So he had 2805 non-fight PIM in 1541 games (reg + PO), almost two per game.
I haven't seen many totals higher than that. Dude was a penalty machine, and not in a good way. (although knowing him, you have to think he took a lot of players to the box with him even without fighting)
