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??

can you move them? just count the turns

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.
