80 thru 85 J truck fuel sending unit.

Just received the BJ's fuel sending unit for my 82 J10. The OHM is 73 Ohm empty and 8-12 Ohm full. I understand that the full/empty has to be reversed in order for the unit to work properly.
Has anyone done this? Any help would be appreciated.

OK...Just checked the TSM which shows 73 ohms empty and 10 ohms full. It appears that the sending unit will work just fine with the stock fuel guage right out of the box. But, I still need to reverse the full/empty ohms in order to be compatible with the new aftermarket dash panel.
Still need help with reversing the full/empty ohms.
