i'm installing my perrin short ram today. my question is: how do you take off the part of the stock air box system that is mounted inside the passanger side fender? you know, the elbow-type piece that is held on by one 10mm nut and bolt with the inlet into the back of the air box. by looking at it, it seems that you have to go through the wheelwell which means taking off the wheel and inner fender well plastic. is this true or is there an easier way to remove it? thanks.
