Zanussi ZI3243A Integral door slider. Need to find supplier

Hi, this is my first post. I hope you can help.

I have a fully integral Zanussi fridge, ZI3243A. It is fitted with nylon sliders that attatch to the fridge door, and identical sliders that fit onto the inside of the housing door.

I’m re-fitting my kitchen, and my (usually) helpful wife has thrown away the parts of the integral door slider that were attached to the inside of the housing door.

I’ve trawled the net trying to find a supplier for these sliders, but to no avail.

Two questions:

1. Does anyone know if I need to buy genuine Zanussi parts, or are these sliders universal, and therefore available anywhere?

2. Any ideas where I could try to get hold of these?

Many thanks

Dave
