The tag may still attatched to one of the housing bolts.
Another way to determine/verify the ratio:
Get both rear wheels off the ground with truck in neutral. Using a chalk mark or some other such reference, turn both wheels one full revolution the same way at the same time (you will need a friend or extraordinarily long arms
). The number of turns of the driveshaft will be the ratio. There may be other methods, but this is what I was taught. GL

Look in the Drivers doorjam itself and not on the door. There should be a sticker with trans, axle and other codes on it. It is usually near the striker bolt.
