Seat frame damage

Hi All, I’ve just bought an RS200 after a long gap from owning Clio’s.

One of the first things I’m trying to sort is the drivers seat.
I took it apart and found the side bolster frame is snapped off at the weld points.
I could get this reeled but I’ve also got 2 snapped wires at the bottom left of the pic.

Does anyone know if this part (black plastic bit) is from any other Clio’s?
I guess anything else would also have had to have had lumbar support too.
Cheers
