wheel cyl. fitting

Here is another ebay listing of the line in question.

NOS MOPAR 1973 DART, VALIANT FRONT WHEEL CYLINDER BRAKE LINE NIB!! | eBay

Mine looks exactly like this. This particular line was manufactured in '76. This is even got what appears to be the same bends. You can see that the end with the long nut resembles a bubble flare. This is the side that would go into the wheel cylinder. Also notice that the nut's threads stop, similar to a ISO European nut. The other end of the line (which connects to the flex hose) is a standard SAE double flare with the threads spanning the entire length of the nut. I'm guessing not many guys have run across this because most throw this stuff away & convert over to disk set up.
