Identify this tranny?

Looks like an A body A 230 to me, The shifter mount is behind the crossmember mount. I think the picture angle is making the tailshaft look longer than it is.

If you can measure the tailshaft.... I have one of these transmissions out of the car, I will post a pic of the one I have after work.

My bet is that is 100% A body
Very valid point. You might be right. Maybe @BrianT could get a measurement on his from the main case to the back of the tail shaft? Then he could compare.
