speedo is easy, remove front plastic cover and pull off needle. Now if like mine it has a little peg to stop needle from falling to bottom in rest mode. When i pulled mine off I know the post moved down a bit. So to get it back accurately I ran at top 3 gears at 45 to get tach reading. used this to reinstall while driving. Then was able to used tach reading to check accuracy of speedo. basically I mapped speed at say 30 40 50 and 60 in top 2 gears then made sure they were all right after swap. Just slide the cluster in with no plastic cover and have a friend reinstall while you go so 50 in top gear, according to tach reading. I know in 5th 55mph is exactly 2250 rpm so that is what I used to pop needle back on. You can do it yourself but easier to get a friend to pop it on when you are driving and making sure tach in top gear is right on a predetermined speed. Not perfect but dang close. ALL if speedo is accurate to start with. or get a cop to radar you in a limited area.
