Just to throw this out there
The 4 dr has a one piece grill, The 5 dr has a two piece grill, the top 2/3 lifts with the hood and the bottom 1/3 is molded to the front bumper. Therefore if it is to be replaced then the bottom must be painted/covered/removed or something. The 4 dr, the grill does not lift with the hood. It is one piece. That is what I meant by easy swap. If there is a product then it should be a bolt on item, i.e. no body work. So far the only 4 dr grill I recall seeing is a Kenstyle, although I'm sure there are others.
