8 3/4 swapped in but....thrust button?

Well Ill be....there IS something in the middle. Should have listened to @318willrun and pulled both axles in the first place! Sorry about that. Here is pic from passenger side with both axles removed. View attachment 1715829102Either way I have green bearings on the way. I can always use them on another diff.
