14 bolt axle hose & fittings ?

[rcrahn]

I need some advice on the 14 bolt rear we've built (with disc brakes) for our project truck. We're now laying out all custom 3/16" brake lines. Having discs on the rear now we'll need a short flexible line to the caliper. Each side will transition to a hard line and meet at a T on the axle, from there another flex line will transistion from the axle to the frame. As seen in the far left of the first picture.
My request is to please see a picture of the fitting at the "T" junction which is sitting on that bracket on the axle.
I need to see exactly what fitting is being used. It appears there's a threaded hole for mounting whatever goes there. Any help is appreciated. Thanks.
