how did you figure out what gears are in the rear

There should be a tag held on the rearend with two of the cover bolts.
The sticker on the hood should say too.
Pull cover and look at numbers on ring gear.
Otherwise you have to turn the driveshaft until the wheels rotate once and count turns of shaft. If only one wheel turns go two turns of the wheel. If you don't have a posi you are better off to leave one on the ground.

CaptainChrysler

It is on the underside to the right of the latch.. It lists options on the vehicle. Could be gone.
