I will post a photo of the fitting on the ad so all can see. Sorry for the confusion. Haha. I am not 100% sure if it will bolt right up. I have never owned a 240 before, just z32's. I have sole many to s13 and s14 owners and they have never complained. Lol. i would research just to be sure. I don't wanna lie to you.
can i see a pic of your BMC third fitting? sorry I didnt quite understand what you said in your post. The third fitting is there? so this is a true plug and play BMC in a s14?
