setting the lash in 8 3/4

I did not take that measurement before disassembly. I did mark the caps. Also I took the suregrip and ring gear out without moving the adjuster that pushes the ring into the pinion. This is what the guy I bought it from told me to do.

So you left the adjuster ring in the threads in the housing? If so that may have helped some.

I would still grab a dial indicator and check it if you can before buttoning it up.
