the 2 door lids slope alittle and the 4 door lids are more flat.
The 4 door lids also have a different lower rear BIW.
The 2 door coupes/convertibles have the U shape rear entry where the middle lights are part of the trunk lid and raise with it, whereas the 4 doors have a "top only" trunk entry, the light panel is fixed and doesn't raise with the trunk lid... thus being Totally different, and will not fit.
Otherwize, you can pretty much grab any trunk lid from 1988 to 1994 off a 2 door, and they'll all be the same, just different spoilers from year to year.
