that Earls adaptor is a nice part - I wish I would have used it. Unfortunately, I have already mounted the relocation kit with a beautiful polished aluminum bracket to the x member. I am using the rubber lines that came with the FF kit and yes the clamps. They seem to be on there pretty good though - I was test fitting it and could not even remove the line when i had to adjust. Will the lines from your Oil kit fit the FF device if I wanted to use them instead of the rubber and clamps I have now?
