Good stuff!

Bill Jacobson installed one in his MGB V8, so they must be an excellent option. Details: http://www.britishv8.org/MG/BillJacobson.htm

Would like to see a comparison between the Chrysler 8 3/4 axle and Ford's 8": weight, efficiency, availability and cost of gears (3.27 and 3.40 options) and narrowed shafts, any differences in aftermarket disc brake options, etc.

The nice thing about the 8-3/4 is that it is a banjo axle and therefore easier to work on and has threaded backlash adjusters but should be somewhat lighter and smaller than the 9" Ford. I believe it has a shallower pinion offset similar to the common Salisbury type axles so it should be more efficient than the ford 8 and 9" axles. With a Power-Lok diff and either of the larger pinions it should be unbreakable in the MG. Even the small pinion version should hold up very well. Weight and bulk should be less than the ford 8.8. There are no c-clips so the axles can be removed without opening the case, unlike many Salisbury axles.

Overall it has a lot going for it and is a viable option for a high horsepower MGB. Jegs carries an aluminum 3rd member. (about a grand)

Bear in mind, The Dodge Brothers started out as axle suppliers to the major auto manufacturers. It stands to reason that they would have a good axle design, even today. Before I went to the Jag IRS with it's Dana 44 center section I was looking hard at the Chrysler 8.75"

It is an excellent rear axle. The only problem it was last made/used in 1974.

It is heavier & stronger than the Ford 8 inch, Curtis. Probably on par with a 12 bolt Chevy. A bit much for most of us. Appropriate for some. I posted this because this rearend has been mentioned a couple of time here, including me. I always liked them.

Stout enough that a friend of mine has had one under a hot rod '57 Chevy Bel Air for many years.

Another good one was the 57-64 Pontiac and Olds. Were popular with 55-64 Chevys when using a 409 or big block.
