Speedometer Gear Replacement
In the process of putting back the original ring and pinion gears on my 03 P71. The second owner thought that a Ford Facing 4:10 rear would be preferred over the 3.27 that came in it. After driving both, I really prefer the 3.27 for freeway driving, that I do to get to work. My speedometer is way lower than my speed, by as much as 15 mph when I get up to 60. I have to get the speedometer gear in the tranny back to factory specs. I need to know the number of teeth on the OEM speedometer gear in the transmission. There is another tooth number as well, I think its on the drive gear, a 7 or 8 and I have no ideas which it is either. I've searched all over but have had no luck finding it. Anybody done this swap and remember?
