There is a nylon block that attaches the inside of the door frame to the door panel. Part number is GNA1374AC. Jaguar says they are no longer in production. Google search doesn’t help either. Anyone know a source for these?

 

I just bought a few from my local Jaguar dealer a few years ago. Did not know that they are NLA.

 

Have you looked for used parts?

Not easy to find apparently.

 

Yes, actually I have. Ordered one from everydayxj.com. It has never arrived. Thanks for the other tip, I will try them.

 

You might find one in a salvage car locally.
Just remember to lift UP when removing the door trim panel.
The plastic part needs to stay on the panel during removal to avoid breakage.

The part is then removed and reinstalled in the door slot.
