Source for stock type oil line to gauge?

[72lb4x4]

I'm hunting for a stock type oil line from the engine to the oil pressure gauge but haven't found one. When I got it the truck had a mechanical gauge from somewhere, but the fittings are different.

The stock line appears to have the threaded fitting and the ferrule as one peice and it doesn't appear to come apart. apparently it was crimped soemhow when the line was made.

I have the line from the scrap yard, and the gauge end, but both were cut when the gauge cluster were removed.

While having engine oil plumbed to the inside of the cab may not be ideal, that was normal and I thought it would be fairly simple to get a ferrule and redo the line, but not much luck yet. If I have to, I'll reconnect the aftermarket gauge for now.

Suggestions?

Thanks!
