Steering wheel not right

Just put new pitman arm in Dart, went for spin and car steers much better. Old arm was pretty warn out and loose. Anyway I noticed my steering wheel isn't lined up correctly now when I'm going straight, it's off a quarter of a turn. Do I need to remove pitman arm and rotate over one click? There's four groove's that line up with steering gear, is it possible I'm one off? Or is this a alignment issue for the shop? 2nd picture is where it's at going down road. I'll check back later, thanks
