Won't work. Inner axle circle is different. If circle is not same, drum rests on studs...rut roh.
I bought these, I know. Won't work on 8.75, it is for a 8.25 rear.

How about this one? More Information for BENDIX PDR0182
I don't see width spec. as 2.5.
But this is close. I think this is the brake drum for the early Dusters with 8.75"

The one I posted was listed for a 1979 D-150 pickup. Early Duster (A body) was small bolt pattern. Never had a large bpolt pattern 8 3/4.

Early dodge trucks (72 -?) Had 8 3/4 with 4.5" bolt pattern.

Correct. That is why I suggested the drum I did.
The Duster only had small bolt pattern 8 3/4
We are assuming the op has A body axles.
If he has b,c,e body axles the center register will be correct.

Maybe you are, but I'm not. Only the "A" body had SBP, and they never had 2 1/2 rear brakes.
How about some context?
What car
What year
What modifications to the rear end / braking system
Exactly. Brake assembly is axle dependent. Without knowing what the OP has any recommendation is just a guess.
1968 Barracuda with Moser stamped differential and Moser axles 5 on 4.5 bolt pattern. Front brakes will be stock Mopar disc brakes.
Do you know if the axles were built with A body bearing spacing or B,C,E body spacing
Very important to know

With front disc 4.5 inch. If the rear axles were made to "A" body specs, this drum should work.
More Information for CENTRIC 12363020
But if they were made to B,C,E body specs you MIGHT need to change backing plates also.
There is a difference from axle flange to bearing retainer A body is a smaller distance. B,C,E is a larger distance
That's a good start. We still need to know which axles by Moser. Specifically, what is the "standoff" or "brake gap?" They were different on A-Bodies. Moser sells 5 x 4.5" axles in both the A-Body and B-Body brake gap. Also needed is the size of the center register. With this information, we can probably figure out what you need. Don't worry about the bolt pattern of the drums. As long as they fit the backing plate / brake gap / register, the bolt pattern can be redrilled.
If you call Moser, they may be able to tell you what you need.
Will not hurt to try. Thought this was going to be a slam dunk with everyone's efforts. I sincerely appreciate the comments. 10 X 2.5 was common on E bodies and 4.5 in bolt pattern. Wonder what Moser would do with that request for axles in an A body rear end. When ordering, it is assumed axles are for type housing. In this case, if you order A body housing you get A body axles. Only choice would be 4 or 4.5 bolt pattern.
This may be a stupid question. What about an E body housing and axles from Moser but have the spring perches fixed for A body application. How much wider is E body housing than A body? This way need only E body rear drum brakes assemblies.
A bunch wider
Have you not purchased the housing and axles yet?
