new rational corner base cabinet, extendable, retrofit

Hello, my Ikea kitchen is about 5 years old. I have corner base cabinets with wire shelves in both corners. The wire shelves are completely broken and hang crookedly because something has broken off. Ikea was aware of this weak point and for a while exchanged these shelves for new ones with solid bottoms. After 5 years, I can hardly expect that. If I buy something new, I thought I would just buy the new pull-out shelves. I am now wondering if that is simply compatible? In the store, they said no, but I can't think of any reason for that just by looking. Maybe someone here knows more? I would be very happy!

Is this about the 90 or 120 cabinet?

I think Faktum 90x90 as far as I could measure it

When it comes to the 90er, I see no problem at all with the carousel since it is mounted on the ground or on the cross connection, I myself installed one just a few weeks ago!

Back then, there was a 10-year warranty. I would take the broken thing there with the receipt.

So, I have had the 120cm cabinet for about 6 years. Over the weekend, I bought this pull-out carousel. Unfortunately, the metal support of the cabinet is more like a metal sheet. However, this carousel is supposed to be mounted on a kind of "metal square tube". My question is, can this support be bought separately? Build it myself?
