Where to get a new shelf for an old EuroCave?

I recently bought an old EuroCave (1990s Vieillitheque Compact, see picture). it's working great but it has this big empty space in the middle. To get the most of the space I need to:

1) Stack many layers on the one sliding shelf that's below the empty space, or

2) install a new shelf in that big empty space with the black bar that goes across.

I'd rather do #2, but I don't know if new EuroCave shelves can fit this much older model. Is anyone familiar with these models, or what type of shelf can fit the holes on the sides of the fridge (see 2nd picture)?

Thank you
