Don't know how far you've got with this but make sure you're using the right chart - I think this is for a Beetle rear end which has different numbers of splines. My bus has 48/52 splines inner/outer and I think this table is for 40/44. It probably doesn't make a lot of difference if you're adjusting both sides equally, but if you're looking to raise or lower one side because the cabinets are making it sag it will matter.
