Newbie/Gearing Question

I picked up an 86 XJ pioneer. 2.8, 5speed manual trans, and 207 TC. The diff covers are missing the tags. The previous owner thought he'd paint the covers and didn't reinstall the tags. I know the axles are a Dana 30 and 35. Anyone have any idea on what gearing it may have come with. It seem pretty low geared.
