Moser 8 3/4 housing is a Ford

Back in the 80s,I used to work at a place that rebuilt transmissions and rear ends and other drivelinechit. I built a lotta different rear ends for about a year. The Ford 9" came to be my favorite small rear. Setting them up was so quick and easy, I could do about a thousand a day, compared to the Mopar stuff. Well Ok, a thousand might be a slight exaggeration,lol. As I became more and more proficient, they moved me into bigger and bigger stuff. I really loved that job.

I really hope he doesn't install new bearings with that petroleum jelly still in 'em.

If you do something for a living day in and day out you get very good at it and fast.
But for the average car guy I still fail to see the advantage of the ford or 8 3/4 being faster to change gears than a Salibury axle with threaded adjusters. You have to pull the axles on either design, you have 10 or 12 bolts to either get the pumpkin out or the diff cover off, you have to drain the fluid on both.
Yes if you had another pumpkin all setup, the real advantage here is your shim packs and your backlash is already setup. But you could do that with a Dana and when you have the right stacks, just take them out and keep the gear sets together.
As the video on YouTube by strange engineering on the s60 points out, with there design eliminating the need for a case spreader, gear changes on a Dana can be done in 20 minutes.
As for the guy in the video, he should have just kept and repaired his 81/4, those rears were a Salibury design and were much stronger than people thought. I used one on the street with an 833 4 speed with 4:56 gears and beat the crap out of it with my 12 second 340 and never had a problem.
The problem with the drop out pumpkin type rears are the axle caps have no side support from the axle tubes like a Salibury design does
That means they flex and distort and the fords 3rd bearing cannot fix that. IMHO
