Production left Poland 8 months back. Good stuff can still come out of Taiwan if there's good QC.

At least it's not China.

My first thought was a 7.5" 10 bolt, and I was close, I think. It looks puny and has the wrong case to be a regular posi, so I think;

Detroit Torsen?

I googled the part #912A317

One would think a Detroit truetrac was made in Detroit.

Yep, it's a trutrac. Apparently there are issues with pins holding the gears in backing out.

So why do you have this?
