i have a 1994 mustang gt 5.0L HO 5speed.how do i determine what the gearing is in it? when im crusing in 5th gear at 55mph the needle on my rpm gauge is slighty above the 2grand mark.when im in 3rd gear crusing i can stomp on the gas and spin it sideways,theres no way that is factory gearing.i was told that the car has had some work done but i really couldnt say if anything has been done without any paper work..i apologize if there is already a thread talking about this.im new here so i dont know how to work this site yet

Jack up the rear of the car.
Draw a line on the drive shaft lengthwise.
Immobilize one wheel so that it can't turn (skip this part if you have a working posi).
Rotate the other wheel one full turn while observing the mark on the drive shaft.
If the drives shaft rotates three and a half times, you have 3:55 gears,
three and three quarters = 3:73
two and three quarters = 2:73
etc.
If you jack up the back of the car and rotate the wheel forward and the opposite wheel rotates in the same direction, you have a working posi.
If you rotate the wheel forward and opposite rotates backward, then you have a non-working posi or none at all.
