i hope someone can help me.i am setting up suspention on a 2003 viper.i have watched the pro action video and this only goes up to 2002,without the adjustable transfer rods.so do you set the rods to the middle(number 2)line,then adjust the sag(having someone sit on the sled,and measuring both sides of the transfer rod)?then you can fine tune it by adjusting the transfer rod?also my sled has a thicker washer on the bottom then the one on the top,is this correct?shouldn't they be the same?
