If your pipes slide all the way to the spring retainer clips you have way to loose of fit. Get the header pipes expanded to take up the slop or you will have an exhaust leak. Look at your frame, you will see a place where a piece of flat bar has been overlayed on the frame. Support your side pipe after connecting to headers and determine where the brackets holes need to be drilled. Drill and tap the holes, you will drill through the overlayed flat bar and frame. I made some 3/8" spacer to go between the bracket and frame so the pipe set level. It is obvious once you get into it.
