Original was probley 2.59 or the optional 3,07 if you have an auto.
3.42 I believe if you have a 6 speed.Mine is an ato so I 'm not to sure about the 6 speed codes.
Auto's came with a D36 axel and the 6 speeds came with the stronger D44.
We need to know more about your car,Auto 6 speed.
In the hatch behind the passengers seat will tell you everything.Do you have the codes G92,I think that was the optional axel code and G44 I think was for my 3.07's.I dont remember the code for the 6 speed optiona, axel.

Assuming it has not been changed then if it is an auto it is a DANA 36 with either:
GM1=2.59
G44=3.07
If it is a stick it is a DANA 44 and most likely a GM3=3.45
I do not think there were any other RPO's in 94 for non ZR1's.

Well....why guess.....just do the math. 
1) raise rear of car, both rear wheels in the air
2) Make a visible mark (sharpie) on the driveshaft
3) Stay under the car, keeping an eye on that mark, and get a buddy to slowy turn a wheel on full rotation (no more, no less)
4) Count the revelations the driveshaft makes during this time period
5) Now you know the rear ratio! If driveshaft makes about 3 1/2 rotations, that would be 3.42 (dana 36) or 3.45 (dana 44), and so on!
