The number of shims will have nothing to do with binding only tooth pattern/pinion depth(that is if they are installed correctly). The only reason I bring up shims is I have seen them slip out of place while assembling. I was only thinking that there is a chance they could be binding on the shaft if that happened.
A change in the number of shims is unlikely needed if you are reusing everything from the original assembly.
Why did you take it apart? Did you change anything? Did you put an Okie bushing in the front?
