Who knows what about early 8-3/4s?

Yup I knew it had been modified to some degree when I got it, if only the 4 link mounts and the splined axles. (Id thought those early ones were tapered like a big ball joint, haven't seen one in a while) I do know some tractor companies back then used the 8-3/4 but don't know what ratios.
I'm thinking garden tractor size like the Pennsylvania panzer.
But this is too wide for something like that.
I'm wondering if it was made for some kind of Baja buggy or some such thing?
But being an 8-3/4 with 4.10s I was more interested in that aspect of it/ even if the housing and axles might be tossed .. and that possibly someone else might see the same thing in that regard.
