torque converter identification

[Lobsterbak]

Just picked up another 200-4R out of a GN...supposedly well built, billet blah blah. But I can identify the torque converter. It's gray, and has "Z"s stamped all around it. Anyone have an idea? Doesn't look to be a 12 incher to me but I havent measured it yet to be sure. It is a lockup.

Owner says it stalls around 2800.

Post a picyure of both sides and maybe we can identify.
