In answer to Carlos' last question first. I put the needle back on the
assembly so it rests at 0, very easy to tell. I am sure the speedometer
scale is not right. It is going to take some playing around with different
gears before I get close. My brother in-law used to repair and calibrate
speedometers. I also used Corel Photo-Paint to scan the speedometer
faceplate and will more than likely move the scale around to make it
accurate before all is done. I also scanned the instrument cluster and
modified the oil pressure to go to 60 PSI. Printing instrument faces is easy
to do with a color ink jet ( or color laser if you got one). Right now I'm
just happy to have a speedometer again, even if is 30 when I'm really going
40.
