Hi, installing a set of louvers on the T/A and I have 3 questions:

1) Does the lanyard screw install on the inner louver support or the outer? This is for the lanyard that holds the pin clip.
2) Does the gasket on the pin install inside the trunk compartment or outside on the exterior?
3) How should they fit when installed? Should they be snug or tight against the roof? Trying to determine how much PIN should be exposed.

Thanks!
