I guess if nobody knows the answer, I'll throw in my 2 cents. In the back of the Advance Store, there are a bunch of black drawers with brake fittings in them. It is a great collection of adapters. You can actually get stock 3/16" brake fittings on the lines, and put adapters on them. If you don't want to do this, you can bring your brake hoses down there, and screw the fittings in to see what size they are. Each fitting comes in a little plastic bag, which will be marked as to what fitting it is. You can then take that, and order the right flare line end. Of course, it would be much easier if someone just knew the answer, but since no one else has chimed in, I figured I would at least give you an idea for a plan B.
