Need help with idler arm ID

Part number cast into it looks like 3402844 N18077
It came off my dart, but the steering was changed to a fast ratio setup with a C body manual box, a Mid-70's B-body Pitman arm and this idler arm. Not sure if the center link was changed.

The new idler arm that was ordered(for 74 Dart) is crooked, compared to the straight one that came off.
