I can take some photos of it from inside for you.
About what I intend to after removing the rack: I expect that the rail will remain in place. That's how I expect to leave it. Except something is wrong with that? I've never had need of a roof rack in my decades of owning multiple cars.
My GX 550 Luxury+ came with a port-installed roof rack. But I do not need one and I would like to sell it. I took delivery 2 months ago. Original roof rack cost price is $1,450. I'm open to your offer. Please contact me if you're interested. Location is Union, NJ 07083. Thanks.
