Is there a specific place that the top cap needs to be drilled and tapped when doing the JKW hydro assist? There were no documents provided to show where the top fitting needs to go. The picture on their website is not good enough to go of of. If any one has the ems or jkw set up and could post up any info I would be gratefull. Thank you. I have searched and found a lot of info for drilling the actual box case but not the top cap.
