from what research ive done i believe it is off of a 92ish chevy blazer
That would be a 10 bolt corporate rear end, whether it was an S-10 or a full size Chevy Blazer. If it's truly a D44 rear axle, it could be from a IH Scout. If I were doing this, I'd consider putting an OEM axle back under the rear end, unless there was a particular reason (width?) that this corporate axle was used.
