I'm looking to do a custom here is my question...are the Oakley "Pitch" frames the same as the Radar XL's besides the different size nose piece? I have an extra Radar XL frame in polished black...I found a decent deal on a "Radar Pitch carbon fiber" frame. If I could swap the nose piece from my black Radar XL frame to put on the Pitch carbon fiber frame I should have a pretty sweet looking pair of Radar XL carbon fiber...minus the polished black nose piece. Mainly asking if the Radar XL lens would fit the Radar Pitch frame once the nosepiece on the Pitch is swapped with ones from my XL's. Correct me if I am wrong but the word "pitch" is referring to the lenses correct? The frame is the same except for the nose bridge which I hope is not a problem to swap. Thanks in advance.
