CK1,2,4. Same light...........basically
What you may have is the "facelift" back end (2001?)
So that "regular" CK lights will bolt on yes, but will not line up with the trunk lid.
Note the different trunk styles and the differently shaped lights to match
That's the only problem I have seen. Other than that they bolt oh. I have seen it before. The only reason they wouldn't line up with the fenders is it the car got hit or something *shrug
Is this the case? Good Luck
