Hello,
if it can be of any help I can send you some pictures of the door sill
without the hinges, as we have removed them for the complete
restoration/respray of my 409. Some pics can be seen in this page:

If you want, I can take some more detailed pics, but measuring the screws
in Imperial threads is not so easy for me!
Cheers
Stefano
