trying to figure out what gears i have in my 93 parts truck.....without opening the covers.

Is there a label on the 14 bolt like a dana 44 has? If so where at and what am i looking for?

Does the vin # tell you anything??

The VIN won't help. If you have the glove box, and it still has the sticker on it, you can read the RPO codes.
GT4 = 3.73
GT5 = 4.10
GU4 = 3.08
GU5 = 3.23
GU6 = 3.42
HC4 = 4.56
G80 = Posi.
