I questioned Jimmy about the mounting. Based on the fact I refuse to deal with the Auto Krafters trim clips ever again. He did say that it goes under the moldings.
The clips actually slide between the rubber and the glass. It has a small L-shape that locks onto the edge of the glass and the rubber sits on top of it while the molding keeps it all tight.
qoute; "Post pics of your louvers" I could not re-size them, so I sent a few of the galvanized louver's... a friend gave me this item so I do not know not one thing about it... it does not interfere with the opening of the trunk and it covers the lower portion of the rear-glass a little more the the original louver...-mel-
