Portable DVD player toshiba 9 inch screen part missing?

I have the above item but we are a part missing. The middle piece where the centre of the dvd pushes in to became loose. We accidentally sent it back to love film when we took the dvd out. Unsurprisingly amazon were unable to locate the disc. Does anyone know if this can be replaced as I have tried all the usual places but without success we thought about buying a broken one off of eBay but don't know if the part can be cannibalised and used again. The DVD player works perfectly
