In the Mustang that hose joins a fitting which is shown in it's mounting bracket in the photo below. The flared hard line attaches to the top and the square end on the flex hose banjo bolts from below. The fitting is clipped to the bracket.



Now the not so good news...I have never found any source for either the fitting or mount other than by harvesting them from a donor car. Unless someone has found an aftermarket supplier you'll probably need to go back to MPS.
