I am not sure what to say for the rating, since I have not climbed this one. It was done as two pitches originally, but it looks as if it could be done in one long pitch The crack looks wide, blocky, and very protectable. If done in two pitches, you will need a gear belay for the first pitch. This probably never had a second ascent, and most likely it is dirty. Treat it as an adventure! I am not trying to sandbag the route, and it may be easier that the given grade. I will talk to the FA and see what they remember and update.
