Sliding sunroof parts

A while ago these little roller things fell from my roof, both not too far apart so I wondered what they did then sort of forgot about it. Now the back of my sunroof has dropped so I decided to find out what they did, anyway I found out they sit above an adjustment spring,  and that both the fixings they go into are broken.  I can now only find one roller.

We had torrential rain yesterday, turns out I might as well have left my sunroof open, it absolutely poured in 😭

So I've had a look for replacements which I don't seem to be able to find although I have found some cables on an American site. I've not had the sunroof out so I can't say for sure if these are the exact part but I think it's the sort of thing I'm looking for



Otherwise ill have to try and botch it up as cable kits and complete replacement sunroofs seem expensive nowadays, but I think that's probably my only option

Anyone have any they'd like to part with? Or know where I might find some? Thanks
