Zanussi Cooker & Hob Main Oven Front Door Glass White 544 x 425.8mm5610437013

Hi Have removed oven door on zanussi Zcv550mwc pnc 948904409 because top hinge fitting is broken (small metal 5mm rod that the hinge rotates around has worn)… I cannot remove left hand side hinge assembly that forms part of the plastic moulding to the oven door even though I have taken off the 3 torx screws that affix it to something!) Do we have to purchase a whole new door and does that come with door hinge inserts to swivel door on oven hinges?
