Z1 Motorsport Premium S/S Brake Lines

2014Z

I purchased Z1 Motorsports Sport Brake upgrade along with their stainless steel premium brake lines.
My mechanic installed the rotors,pads and from brake lines but the rear lines are too short. He stated that he could cut and remove some bracket to make them fit.
I got ahold of Z1, but they were no help at all. They just wanted pics to see what the problem looks like.
Has anyone had this problem before? I have been using this mechanic for many years and he is an extremely honest individual and friend.
My car is a 2014 Touring/Sport with a M6.
Any help here there?
