[Milsurplus] BNC pane lmount sought

[W2HX]

Hello all again,

My RT-618A must have been dropped on its rear.  The BNC and N bulkheads must
have been hit and bent the enclosure.

The N connector survived, but the BNC was crushed. I tried to round it out
but with no luck.

I was able to get the inside separated from the outside. Anyone have a
replacement that kinda looks right?

This BNC has a flat on one side. My parts bin seems to only have front-mount
panel mount BNC's hoping to find the correct rear-mount.

This has the following stamped on it: KINGS KC-19-46. Anyone?

Also, this aluminum enclosure is proving quite difficult to hammer back. Any
advice on how to straighten this? 

Thanks
