Nylon Line Attached to Line
The nylon line attached to the new line is not a direct replacement. It is only a section of nylon line that will splice to the original nylon line on the vehicle.
On the opposite end of the original nylon line, there are connectors. These connectors may be damaged during removal. If so, we offer repair kits with new OEM connectors. These will, also, need to be spliced onto the original nylon line.
