Desperately looking for drawer dampers for an old Ikea kitchen

Hello, can you please help me, I am new to this forum?

Back around 2005, I built a kitchen myself and bought Ikea full-extension slides for it (Faktum? Rationell?)
Now I would like to install dampers for them, if they exist.
I have posted a picture of the slides, could you please check if there are dampers available for them?
Alternatively, I have heard that you can just replace the rails with newer ones that have dampers, do you know anything about that?

It would be nice if someone could say something, I’m already curious!

Cheers, viggo

Hello, there are no dampers for the rails. It was only in 2006 that the rails were extended with a bracket for dampers.
