The easiest thing to do is contact Dee/Harry at Flying Scot. They can sell you the correct type of line, the correct length and the additional hardware you will need. You will be supporting the class and help keeping our builder in business. Flying Scot also provides detail instructions on installations that are probably not needed for your installation but good to have for others. Remember to connect the line at the block to the track per class rules. Dave FS 5690
