Is there a manufacturer out there who makes the interior cardboard door pockets for the 150
There are several different shape and finish (flock or vinyl coated) door boxes depending on the year and model XK150.
World Upholstery in CA USA should be able to help 805-921-0100
Well it seems World Upholstery no longer produce the door pockets, however Bas do, so I have requested more info re pricing, covering and delivery.
Thanks very much for the contact info.
