Help with rear axle

[bj383ss]

I need help identifying my rear axle. I tried to look it up but my letters were nowhere to be found. These are from the axle tube.

TDE 0514W2

My mother in law said she remembered helping replace it. Just curious what it came out of. It has bolt on backing plates and the pumpkin has the mount the panhard bar bolts to. Its a 12 bolt 6 lug but it does have 30 spline axles. Non posi.

Thanks in advance
