I'm sorry, but that's not a Kappa outside door handle (should have 2 machine screw receptacles at the back end).They used to grease the spring to eliminate squeaking. Might want to slap some on there before putting them back into your car. I finally found the 2 chrome ones I have from the good old days of being a GM handle engineer. A bit dusty after 15 years 😂
But then again, I stayed at a Holiday Inn Express last night.
