I'm going to say those would be a tough fit.. The halos and shroud seem to stick out pretty far, and both the 05-08 and 09-13 frontier headlights are very shallow. For me to fit the FX-R's I had to cut the bowl and seat the projector with the back third sticking through the reflector bowl, and even then the shrouds have clearance issues. For the TL's I'm running now, half of the projector is sticking out the back of the reflector bowl and that's without shrouds. Because I used custom made shrouds I was able to let the projector sit more forward so the lens is only about 3/4" away from the headlight lens. As far as the diameter, The 09+ lights have more room but the turn signal protrudes into the reflector a lot, so you would most likely have to cut something. For 05-08 you have plenty of width, but next to no height, so again you will have to cut something.
