Amici I have a TR4A rear end here that seems to spin in the 2-1 range?? When one wheel is held and the driveshaft is turned 2 times the wheel has made 1 full turn.Going to pull the cover off tonight to look further into this.I don't know of a ratio this low........any one??? it's a later model...guessing 1967.(parts car)ThanksMike Deweerd TR4 #77
