Not really, have a glove box sticker. RPO for the gearing will be a G something

I don’t think the 14 bolts have anything like the BOM on the Danas. I have learned the hard way not to trust those anyway. The pinion and ring gear tooth counts will be stamped on the rim of the ring gear though.

Years gone by and things change.
As Greg stated pop that cover.

Look at the #
That is the only real way to know for sure.

About a gallon.


If you have had the axle out and the wheel bearings are dry maybe more.
Make sure to jack each side of the axle up and let the oil flow to the bearings.
If not a gallon will do.
