Best to check manual for removal. You’ll need an inch lbs (19 and 71 inch lbs)torque wrench when installing

i installed mine onto the trunk lid with wing and base plate together

you’ll need to replace the weather seal

i used white rope putty seal

can snap a picture of the box tomorrow if required

Don’t over tighten.

If you have a roadster, now would be a good time to repair the cracked wing. All roadster wings crack
