can someone send me the instructions on how to install them? (how to modify the maxima to install the cefiro headlights?)

ok, there's a bracket on ur fender that holds the headlamp and the corner lamp together, since the cefiro is just 1 piece, that bracket is not needed and instead is on ur way stopping you from a perfect fit. so just cut it off and cefiro yourself away. also you'll have a 1/4" gap on the sides, either fill that with rubber strips or have a body shop put some bundle if you are in new paint preparations.
