Anyone Installed 3 Point Belts in a '60?

[Too Slow '90]

Sorry I didn't get back to this earlier after asking a bunch of questions. Thanks for all of the pictures and advice. They are installed and according to the manufacturer are correct. I am still not sure that it makes sense as they do pull across one another when not in use but seem to function properly when used. Thanks again for all of the help. Hopefully today will be finishing the front disc brake conversion and I will be on the road again.
