8 3/4 identification. 391 gears

[hwy2]

Where do I measure to find axle size
Seems like this one could be this size ot that. I just acquired the whole assembly. Trying to figured out what it is exactly. Measures to my duster. Seller knew nothing of it. Duster has a 7 1/4 now I think.

i'm not sure entirely what you're asking but here's a measurement chart for the rear end and axles

An accurate 8 3/4" rear axle width list

Ok, so, I've posted parts of this list a few times, normally in response to some of the really inaccurate charts and lists that are out there and posted too frequently. It's not my list, I sourced it from the internet but I can't remember where. Since the time I downloaded it several years ago...

if you're asking how to ID the gears you can pop the carrier out and it'll be stamped on the ring gear or you can turn the axle and count the revolutions on yoke.

Yeah I agree your question is rather vague.
Do you want to swap it into your car?

I an just trying to figure exactly what it is. I think from fist post here I may have figured it out by numbers. I just want to get right parts mainly all bearings I can replace
