Model A Rear End Ratio

[Afordman31]

Jacked up the drivers side rear wheel, put a piece of tape at the 6 o'clock position. Put a mark at the 12 o'clock position on the drive shaft splined end.
I then turned the rear wheel forward one full revolution and the driveshaft moved not quite 1 7/8 turns clockwise. What ration rear end do I have? Your help is much appreciated!
