I need to know how long is the stock rear brake line in inches for a 2001 929 cause ill be purchasing a chrome swingarm and chrome swingarm extenders for up to a 4"-6" stretch? So just needing a length in inches cause whatever it is ill be buying a longer rear brake line at least 6 inches longer than the stock line!

 

Youre gonna need a 34" brake line and that will get you up to 6 inches. You can buy them from ebay for less than 40.00 bucks. Better to buy a braided line then have somebody fab you one. Here is the link for what will work.
