because the question was asked above, let me help out with an answer.... to be legal youre going to want to do more then just swap the trunk lids..
to make it so you arnt left with zero third brake lights, and the other car to have two third brake lights. you must swap the interior trunk deck peice also. its a direct swap, and the wiring is already there for the third brake light. take your time the interior comes apart easy lots of clips, some screws.
keep in mind also that you are going to need to swap the torsion bar (springs) that assist the lift of the trunk. if not they will be way to strong for new non-winged trunk lid. its going to double as a catapult, and the other guys trunk wont stay open.
if anyone is doing this in the northern new england area im willing to come help for some gas money. i even have a tool to help with the PITA torsion bars.
