2007 express brake line fittings

I'm in the middle of replacing the rear wheel to wheel line and from the splitter to the rear line on a 2007 Express. Pretty sure both lines are 1/4 inch. The fitting on the splitter under the driver's seat is a 1/2-20, the other three are fine thread and i cant find them anywhere. They go from wheel to wheel (connect to the rubber lines) I found fittings with the right threads but none with the right threads and that will fit on 1/4 brake line. If anyone has done these they probably know what I'm talking about. GM definitely didn't make it easy to service brake lines on the express, searching online looks like the Silverados are the same.
