dana 30 ring gear torque specs

I have a 88XJ I am looking for the specs on the ring gear and caps, I have searched and found other axles just not the 30, other sites refer to different years have different size bolts with different torque specs, either 55ftlbs or 70-90ftlbs but know one new the year cut off or bolt size. Does anyone know what the XJ uses?

Thanks
Donald
