my 945 came to me with the anti-rattle kit already installed and completely ineffective. I experimented with double-sided tape and adding shims to the anti-rattle add-ons, and none of it lasted more than a few days. My solution is below.






Placement of the screws up top is key. There's wiring and wiper system stuff that you absolutely do not want to damage. Mine are not elegantly arranged (I'm a bit OCD, so the fact that they are not symmetrically spaced would annoy the crap out of me if I could actually see them while driving) but these were the best placements I could find where there was a reasonable margin of safety that the drill bit would not go rogue and ruin something.

The big screws are all #12 2" or 2 1/2", the small ones are #10 1 1/2".
It is important to add a little nickel anti-seize to the stainless screws to reduce the likelihood of galvanic corrosion in the aluminum tailgate.

It doesn't look very nice, but it is finally quiet.
