Try spraying the hell out of it with PB Blaster and let it soak. I have brought petrified rubber back from the dead with it. Rubber hardens from the lose of the oils in it. I guess the PB penetrates are replaces some of those lost oils with itself. Depending on how hard it is, it may take a couple rounds and soaking to get it presentable.

I never tried a piece as big a running boards. Usually just smaller pieces that I could put in a zip lock bag and let soak for a couple of days.
