If you have overdrive, it's a 200-4R.

Look on your RPO label under your trunk lid. You can look up the codes to tell what gears you have.

First, use punctuation marks. Reading a post like that leaves the reader breathless.

As for Posi, if present, the Service Parts Identification Decal (SPID) will have code G-80 on it. The axle itself may have a metal tag on one of the cover bolts stating the need to use limited slip diff lube only as well, provided it hasn't been lost to time. The gearing codes will also start with a G. GU1, GU2, GU3, etc. If you post your G codes here, I can translate them for you. There is also an RPO code sticky in the knowledge base section of the forum that I wrote detailing the common RPO codes.
