Dodge Challenger Window Louvers

if you can afford it, don't go polymer - especially if you have a Shaker scoop that's aluminum; this louver is very complementary to the '70s aesthetic of custom car fabrication; its light and simple bent-metal, riveted construction looks like something you had made by a skillful metal shop instead of a mass-produced product which it is; no issue with design, build quality and finish - but let's talk installation and security; the post plates that you attach to the glass to secure the louver to the window uses strips of 3M tape that are a bear to deal with; I estimate I spent more time trying to peel off the tape backing than any other phase of the installation! Very tedious! I then covered the exposed 3M tape with strips of freezer paper (much easier to remove) so I could position the louver with precision during my one-man installation; success! Now consider security - you just spend hundreds of dollars on an accessory someone can lift off your car without any tools; I've since purchased #10-32 (tpi) tri-groove security nuts and the corresponding socket to lock this down because the plastic finger nuts supplied with the kit are asking for trouble; BTW, anyone selling this item used without the mounting plates is selling a stolen product, just saying; good product; would be excellent if they made the backing tape easier to deal with and provided security nuts instead of common fasteners.
