2003 Buick Lesabre complete kit. Master cylinder lines needed the most tweaking didn't include flexible sections like oe. The other lines were slightly less than hoped as far as fit for Labor involved to install. But still way better than installing new unbent steel lines . I'm guessing that using the universal copper nickel brake line would be slower but not sure how much. The massacre would be if lines were prebent using DOT certified copper nickel line Hey, InLine you should offer the DOT certified copper nickel brake line for an option since it doesn't corrode and tweaks the easiest for install I will try another kit in the future when the need occures. Overall these prebent kits from Inline are absolutely the way to go. Just need copper nickel line option to be the best and fastest for install. I'm tax exempt repair shop the web site needs a way on non business hours to allow for submitting resale tax number as part of the order & following it up with a with a faxed or emailed verification copy within ? hours of the order as part of ordering online process !!!!!!
