Yeah I was going off of that Picture, although I didnt catch the rotor housing but your right since on a true 20B the front intermediate plate is like double the thinkness of a normal one.
Now that could be 13G though I don't remember but I thought they had a thin front intermediate plate, at least the picture of racing beats looked that way
