For those in the crowd who have not had this done for them, what is the interior door panel made up of??
I haven't really seen any photos on it and wonder if its a bit of a custom thing??
I see map pockets and thats about it. I am looking for input so I know what the heck to do with my unupholstered interior. I went for leather seats and thats it. Now I have to carpet it and cover the doors and dash.
So I wonder if I start out with cardboard templates which then transfer to hardboard which is then covered in the appropriate covering??

One more question what has been the norm for covering the read bulkhead behind the seats??
Carpet ?
TIA
