Steering wheel 180 out on new to me ZR2. So long story short, bought with blown motor, installed new motor with headers and pulled steering shaft. No time in vehicle so I don't remember steering alignment when drove onto trailer. Is there any possible way the steering shaft is 180 out at firewall? I confirmed it is correct on gear box. Is it likely an alignment will fix this, or Is it likely that someone changed pitman arm and installed it 180 degrees out? I'm leaning towards Pitman arm is 180 out.

Thank you all for your help. I tried to keep it short and to make sense.
