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

It doesn't. At least not in print to me. I'm kinda thick when it comes to reading text and applying it without pictures sometimes. But then, I'm kinda thick anyway. lol Any way you can post a video?
Unfortunately don’t have a video. And can’t get one for at least a week.

Another thought I just had, is that issue is possibly brake related. Front discs, rear drums. The rear wheels are acting like they are getting caught on something when spinning… so they hesitate(slow down) then spin forward normally for about a quarter turn( of the rear wheel) then seem to get stuck(hesitate) again.
