Ventilation parts - LEGO ?




I was able to find all pieces on side vent and glued broken tabs to make it working, but the "forks" in lower center of the pictures are missing on center vents.
Small parts, not likely available separably anywhere but they change direction of air and are kind of important.
Anybody has an idea how this can be fixed?
I can buy center vent on ebay for about $100, what would be PITA to spend for 2 small pieces, but additionally what I can buy is from prelifted cars and I am not sure those pieces will fit.




What makes me wonder - howcome ebay has plenty of parts for prelifted models, but none for postlifted.
Could it be that assist programs prevent accidents?

Do you think gluing them to the shaft they attach to would be a viable solution? That would probably mean that you won't be able to take them without breaking them even more, but it is the cheapest option I can think of.
Or you can manufacture the broken part from a piece of sturdy plastic, glue it on where the forks are missing and file it until it fits. Best scenario would be you own a 3d printer and like Fusion 360 or any other CAD software, or know someone who does.




I spend about 1/2 hr just putting together the pieces I was able to find for side vent. I guess factory procedure to install 4-way swing is install horizontal blades with pushrod, than slide the fork into place with bottom of the black bracket and lock it with silver cover.
Since I had to glue broken tabs, I had to do reverse engineering.
Anyway, found lifted part on Polish site and email the seller about shipping to USA.
Hope can get whole center assembly for less than $50, what would be good deal considering.
