2006 Corvette Fuel Sending Units Discontinued, making 07+ units work

I'm trying to get my 2006 Corvette gauge to work correctly again. The 05-06 sending units are discontinued and I was only able to get 08+ fuel pump and passenger side transfer pump (Delphi ft4031, which included 08+ sending unit)

I am told GM switched the resistance for the 07+ sending units but I don't want to mess anything up. I have HP tuner, I do not know what values I need to make the 08+ sending units work on an 06 car.
