Hi [tbreay](https://forum.digikey.com/u/tbreay),

Welcome to the TechForum.

The nearest part I have found is the [1757821-1](https://www.digikey.com/en/products/detail/te-connectivity-aerospace-defense-and-marine/1757821-1/4486538). It does take the same contact.

The difference is that it has a “floating bushing/washer” placed over the mounting holes which reduces the diameter of the hole.
