What rear end gearing would be normal for the Ninety-eights to come with (1981)?
Thanks in advance.

Hi. I am suprised you have got no replies by now. Do you still need this info. Let me know. I have a shop manual that may help. Jim.

The 98 had either 2.29, 2.56, or 2.73's out back. Look on the trunk lid for the "GU" code.

I upgraded from the GU2 to the GU6 in my Delta
