Factory 72 oil pressure gauge connection question

[turborambler]

Can I get what I need to fix the factory oil pressure gauge connection at the back of the dash from O-reilly's or AutoZone? It does not look like a standard compression fitting and I broke it right at the back of the gauge where it goes into the small hollow brass fitting. I know I can order a kit online but if I want to try and get this locally today. Or if Napa or someone else has a way to fix the metal line end and make it work I am cool. It looks like it has a slight flare on it after it is put through the hollow copper part on the back of the gauge.

Thanks for any help!
