Ls1 rear brake problem

[Jameson]

Seems like I keep going one step forward and 6 steps back here. I am trying to adapt the C5 brake hoses that are M10x1.0 ISO bubble flares to the stock Monte SS hard lines, both are 3/16 so im ok there but I cannot find a M10x1.0 line nut to go on the line anywhere. I really dont want to have to go to the dealership but may here, But in the GM parts lookup at the dealer they call it a Inverted flare for some reason despite it being a ISO bubble. Im at such a loss here and about to spend more $$ on a set of braided lines just to use a double flare instead. Im really racking my brain here, I dont need braided lines on the rear and the rubber will work just fine but im going crazy here. I picked up these C5 rubber lines because they were longer then the F-body lines by a long shot for better routing.

I believe this is them but dont know why they are refered to as ford? Its a M10x1.0 thread and 3/16 tube.

some thing like http://ls1tech.com/forums/conversions-hybrids/1233163-my-67-camar0-ls1-4l60-swap-thread-13.html post 251 should work. if you wanted to spend some more kore3 has lines that should work for you.

I don't have the stock style any longer to use an adaptor, its silly to me to re-flare to stock and add more junctions for it to leak later on when I can do it right the first time with the correct fitting.
