Advice on where to get a banjo fitting

[Love 70 Chevys]

Looking to replace the flex hose banjo fittings on the front drum brakes of my 1970 K10 1/2 ton. They are tapped to accept a 7/16-20 male thread on the flex line and use a 7/16-20 banjo bolt to the brake cylinder. They are a little odd in that the fitting creates a 45 degree angle between the line and the wheel. Can't seem to find anywhere! Also, if anyone went to a "plan B" on this, please let me know what you did. I have one that I could probably re-use, but out of luck on the other side.
