File down the liftgate lock cylinder housing to expose the spring and plunger
Install an M6 by 6.5 mm screw to secure the plunger.
It looks like the first image you have shows the lock cylinder housing after it has been filed, is this correct?
Loctite has about 10 different kinds of sealer, is there a specific one that would work best for this application (by name or color). thanks?
Yes, the first image is after filing, blue loctite is recommended. Thanks
