They have generic ones, and ones specific to the model year. For my Corp14ff I simply went down to my local parts store and got generic ones and bent them myself with a hand bender. For my D60, I ordered them from inline tube. I also got my proportioning valve from them for my conversion to the rear disks. If you get the right ones for your application, they will fit perfectly. I have an 86 K5 but nothing much is stock on it.
