Need Help - Scion tC StopTech Brake Lines

Wrong forum I know - my g/f is cross posting in a Scion forum too. We tried to install front and rear Stoptech SS brake lines on her '08 tC this evening before she goes to an autocross event in the morning.

The rears installed fine. We had problems with the front. I could get the front lines to bolt up to the caliper but the stock 10mm fitting at the end of the stock steel line would not fit into the end of the Stoptech line.

The stock 10mm fitting would not set deep enough into the Stoptech fitting to allow the threads to bite and pull the fittings together. When I took a careful look at the insides of the stock and Stoptech fittings I noticed that the cone inside the fitting is slightly more pronounced on the Stoptech lines. I think the larger cone is keeping the fittings from connecting.

So...she bought these things on eBay and probably can't return them. The event is tomorrow. Is there some special tool that compresses these fittings together? Do I try and dremel the the cone down? Postpone the event and have her call Stoptech on Monday?

In this picture, the area circled in red is what we were having trouble with. The brass colored fitting is the end of the Stoptech line. The black nut is the end of the stock steel line. I can't get these two close enough to engage the threads.

-Thanks in advance for your help!

 

I think that folks who have installed the StopTech lines have needed to remove part of of the stock bracketing to make the space to get those fittings together.
