Subsequent installation of roller blinds in rear doors

Hello.

Unfortunately, my recently purchased D2 BJ 1995 did not have any blinds at the back doors and the little ones roar when the sun is dazzling.

So the rear blind and both blinds were bought for the side windows (yes, there are currently door boards with Rollo at Ebay, but unfortunately not in Antrazith 4D0 867 306 AK and I don't want an interior that shimmers in all tints, like a papiagei).
I had already bought the door panels in Antrazith anyway, in order to install discreetly in place of the "Nokia/Bose" correct loudspeakers.

The cartridge in which each of the blinds is, fit into the door panel, but of course in the door panel all mounting options for the blinds are missing.
The metal roll-ocarcase itself has a metal lip over its entire width, in which there are 6 screw holes.
However, the attachment to the door panel is missing.

Question 1: Does anyone have experience with retrofitting / fastening these blinds? Can I screw it on somehow, or do I have to glue it with the help of synthetic resin?

Question 2: It seems to me that the chrome strip attached to the door panel must be removed, or does the chrome strip of the door panel remain?

Question 3: If the blinds of the side doors are pulled out, they can probably be locked in three hooks on the upper door frame. How can these recordings be retrofitted, please, because someone has experiences? (Even if I buy some from Ebay, they are missing, of course, because these hooks for mounting the pulled out blinds probably should be attached to the door frame)

I have already looked in the search function in the forum, but so far no one seems to have retrofitted blinds for the side windows.

==References== I use photos of original installed blinds in the back as they sit in the door and how they are pulled out above.

An image of a roller blind as I imagine, that it should be installed but still to be fixed (cf. Question 1)

Thank you

Tom
