Thanks for the info everyone. As i look at it closer the mystery hose is definitly in the middle of the brass piece. I can get the rear axle brake lines and hose for about $70 or so. Just want to get the brakes set up before i start on the exhaust. Plan on headers, with a set of moderate sounding mufflers. Maybe flowmaster, but then theres alot of those out there and some people think they are loud. Maybe magnaflow. I also plan on exiting the chome tips out of a GT valance. Though I will probably just cut the one i have and get the trim rings seperate. I like the clean look of the exhaust out the valance versus hanging below it.
Thanks..
