Retrofit Rollos doors rear

Hello.

Unfortunately, there were no blinds available for my recently purchased D2 BJ 1995. Heckrollo and both of the blinds for the side windows I used to buy.

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?

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?

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 in a state of development and one like me imagine that it belongs to it.

Thank you

Tom
