I am looking for a Pentax ME camera parts (specifically focusing screen) to fix up a camera.

I have optics background and the camera we have is working perfectly other than damaged focusing screen, so I am confident I can fix it and bring it a new life. I know many people have broken cameras around the house that they do not know what to do with so let me know if anyone has a Pentax ME that can be donated for parts. This camera is not very valuable so when trying to order parts online the shipping is twice the cost.

Thank you for any help you can offer.
