I still would prefer to have some pictures with your otherwise very descriptive instructions, Kuhl.
Tried taking the door trim of today following your instructions, but stopped when I felt afraid I would be breaking something.

Too bad the Service Manual is still "out of stock" according to Helm Inc.
But that might easily mean, that it was never in print?
