None at all as I sent it to my local shop and let them do it for me. Just don't have the lift or tools to go in and without the know how I'm not afraid to pass it on to someone who does. They did mention it took a couple try's and a call over to Patrick to get it set right but then again I don't imagine trucks this old come across the shop every day. Runs great now. Just need to get the speedo adapter so I can now exactly how fast I'm running.
