Take the dash apart again and remove the clear plastic cover. Remove all the needles and very lightly reinstall them. warm the car up and put the needle where you want. The gas too put where you want and what you think is right. A good way to judge is the low gas level light. It should come on at about 1/8 tank.
The rpms on a fully warmed engine should be in the neighborhood of 800-900.
The speedo you will need to set with a stop watch, the odometer and some mile markers on the interstate.
60 mph = 60 seconds to the mile
55.4 seconds = 65
51.4 seconds = 70
48 seconds = 75
45 seconds = 80
When you get it steady (with the cruise) seat the needle good.
