On mine that was not the case. The front mounts slid forward underneath the rubber gasket beneath the chrome trim. I don't recall them using adhesive. No trim was disturbed.I assume the chrome trim around the hatch , has to be removed to install these. What do you use between the mounting brackets and the glass? I can’t find any install instructions anywhere
I remember OEM louvers available in 77 for the Zap edition and in 78 for the Black Pearl ( see photos) but not for the ZX starting in 79. The 77 and 78 special editions were modified by Nissan once they reached the US.
