i did it with mine, take your take and be precise(i wish i did) my gas gauge way off and same with my temp gauge, but it can be done if you take your time! and just my opinion it doesnt look that much better(even though i did it)
I just did mine, I took a bunch of pictures first, some while driving, some at idle, some with the car cold and the key on.
I was able to set the 4 outer gauges with the key on and the car cold, just wait for a while to do the gas gauge, it takes a while to come all the way up. Then I set the Speedo, I had a friend set his Cruise control at a whatever speed, then I was able to put my needle on while following him at that speed. After that was set I went back to my pictures and found out what I was taching at different speeds, I brought it up to that speed and set my tach needle, then double checked it at other speeds that I had taken pictures of. (First I tried to just set the tach and speedo against the stops, but they were off, do NOT trust that route!!)
