Duster Rear Window Louvers

the louvers on the white amx are factory, black amx has aftermarket ones from way back when, The vega i used side louvers from amx and a rear louver froma datsun 280 and made them work, and roadrunner was an aftermarket piece from late 70's.

To attach the bottom you could make a clip that goes under the trim. My amx has 4 metal tabs.. say 1x2 that have a metal stud up into the louver with a nut. The tab is pushed under the trim. For extra insurance I used clear rtv on the bottom of the tabs and clipped them as well.
