I have done a lot of 8.8" Ford Units in my younger days. If I remember correctly the manual instructed to slide the shims in by hand to set backlash. Once correct backlash was set it said to increase each shim by .004. That was very tight so I mostly increased them by .002 on each side. I had all the shims Ford offered and 2 of many. They got crazy on the pricing so I switched to the adjustable stack shims.

My GM and Mopar buddies all used case spreaders. The solid shims could be installed by driving them in. The stacked shims are a bit more fragile.

Good luck!
