Does anyone have the correct GM or Delco part numbers for 2007 with Z55 Premium Autoride Suspension and 22" wheels? Premium Autoride is the electronic controlled (valve turns in shock), but not the later Magnetic Fluid. The correct shock with 18" whels is 19300037 but I need the shocks for 22" wheels. Correct Monroe part number is (I think) 40049. Thanks for any assitance.
