How bad?

My dad got a 9 inch ford rear for his 27 T roadster pick up with 4.11 trutrackloking sureposigripping gears. He took out the 3rd member to get some brackets welded on the housing and we were cleaning up the pumpkin and I noticed this.

Here is the other side.

The old bastard with his rear in a bucket.

The gears are very smooth and there is no binding or anything that feels bad when you rotate them. The axles both slide in and out with no problems but there is this chunk taken out and a round wear section that has nothing wearring on it.
I ran a magnet on a stick into the pumpkin and came up with nothing major. The housing had the usual teeny tiny metal bitts inside.

What happened to it?
