Sounds like you already solved your problem, but just in case anyone else is looking for the same answer...
If you order the correct intermediate brake line, that little 90 deg piece usually comes zip tied to it. Look for "2pc" in the description. I just replaced my intermediate line and that short 90 deg bend from Fine Lines / SSTubes and it fit fine. Part ZIN6704OM in my case. I would bet Classic Tube does the same.
One caution if searching NPD, there is an item 2B092-1A that says proportioning valve... 67 Mustang... and sure looks right by the picture. It ain't. What shows up doesn't match the picture. Dumb me should have known from the description it wasn't right, but was desperate enough to try.
