The Scangauge II that shows the MPH, RPM, temp, and fuel level, but the stock odometer will show the RPM and MPH.
The oil gauges have internal bump stops in the motors so they were the easiest to my surprise, I could calibrate them by hand in the house.
Match the RPM and the MPH the stock digital read out and stick the needles back on. I put the tach needle on while hanging the engine at 3k for accuracy in "driving" RPM.
Temp, wait for the fan to kick on and stick the needle straight up.
For the fuel level just take a picture, that's about the best you can do with out some kind of other reference. I did use the picture method for the fuel and it worked perfectly, the percentages on the scangauge matched the needle as the tank emptied.
