Will an 8 3/4 rear end fit in a 73 dart sport?

Update:

I pulled the driveshaft

I had the car jacked up and I could rotate the passenger wheel about two inches, and the joint from the driveshaft to the center section would barely move. When I did this to the driver side, there was no play. When I moved the driver side wheel, it was perfectly in rotation to the third member gears.

I have the passenger axel out, but the driver side axel is stuck.

I have all the bolts off for the center section but I think both axels have to
Be pulled out from the center. Is that correct? The passenger side wheel bearing seems to be ok.
I’m aware this is a ford rearend in a mopar forum, but any insight would be appreciated. Thanks
