Updated: post #9 1996 K1500 with a 5.7/4L60E/241C This truck has a driver side drop transfer case and needs to be replaced with a passenger side drop transfer case. The truck has a SAS and has a GM front axle, therefore the need for a passenger side drop transfer case. Will a 241 from a 88-91 Blazer or Suburban work? Will it bolt to the adapter that is currently in the truck? Will the VSS work with the Vortec computer? Are the wiring connectors the same? Will the speedometer need corrected or work the same? I don't know much about this stuff... so any additional information or suggestions would be helpful. I do know that the t-case shift linkage will need modified.
