Need help identifying a steering box

Well now don't give up yet.Check the mounting bolt pattern. Remove the rag joint at the splined shaft. Remove pitman arm. If splines match you can reuse the car parts I.E. pitman arm.Steering shaft coupler is different between manual and power box.The column steering shaft is longer so you need a shorter one or cut and go with a aftermarket coupler. What ya workin on ?

I have a 67 Barracuda, going from manual steering to power. I have the steering column, the pulley, pump, hoses, and brackets. I'm only missing the box.
