So to make a long story short I am instaling a different middle gear in my 88 venture, so I wanted to know when the back lash is to be checked in 4 different places should I have the very same back lash # in all 4 places or can I be any where from the min to the max setting as given in the book, because it looks like there can be 2 shimes on one side and 1 on the other, And if I was to use that blue dye to check my work would that work on the way the venture is set up Thanks.
