Yes, absolutely get rid of the map pockets. They were such PITA on my fox body and by that point they didn't hold anything anyway lol. I cut some carpet to match to replace mine but I'd much rather have those vinyl plates.
Yeah the sagging got so bad on mine at one point that they doors wouldn't shut all the way because they would get caught in the door jambs lol. I put a cable through them to hold them up, but those vinyl inserts will look much, much cleaner (and more modern to boot)
Yea I agree it will look a lot better then the map pockets if mine had the pockets I think I'd get that piece but hey maybe you like and use yours but obviously not enough cuz your considering replacing them lol long story short i vote change um
