Hi, replacing door parts on a microwave should only be done by a pro. Anything that interferes with the door setup must be checked out afterwards with a professional microwave leakage detector. If you are UK resident the parts are readily available, BUT watchout for the horrendous pricing from Hotpoint. Robin Hood has nothing on these guys. I would expect to pay no more than £10 to £20. Anymore than that vote with your feet.
kindest regards
