Hey Nick, I see something about changing Diff fluids out. Anyone explaine that any further , I have a AVALANCHE, what would work better in the Diff Case?? Also other than the Clutch Bell due out Monday with the 12 or 14 Teeth, is there any other Brand Name or Part number I could use just the same?? Can I leave the same clutch Bell on the AVALANCHE and just change the Teeth out??
