Need help, part 26-351 doesn't measure up!

Hi the part 26-351 that matches the measurements on web site were received (thank you) but they do not measure up in regards to either screw hole, the width or the length (see the pictures attached).

Might you the part matches the measurements on your site as well as the measurements in the pictures? If you need more precise measurements I can send them.

Thanks again, you have been very helpful to us.

Judy and Steve
