These titanium replacements are a huge improvement over the weak stock pieces. Secure your wing windows properly with this overengineered replacement. By replaceing the rivet with a shoulder bolt you can now fully disasemble the system allowing for rebuilding, cleaning etc. The titanium will stay shiny (unlike the pot metal originals) and will outlast the rest of your car by generations.
Kit includes two of each titanium part: exterior bracket and interior washer, interior screw, exterior shoulder bolt. Also includes required four rubber gaskets.
 
To install, remove the screw from the inside, remove the rivet from the outside and clean glass. Then install the the new parts sandwiching the gaskets in the same orientation as the parts you just took off.  We recommend a tiny dab of locktite on the female threads. Thread in the screws and tighten. Be careful not to overtighten as the screws are very small and too much muscle will snap them off.
