4" lift question

[VonDog]

The steering arm seems to be newer for the lift but the pitman arm seems to be original - does this look correct?? And while test driving, one way turns more than the other. Can I get better steering by putting on a drop pitman and finding center on the steering wheel??? Never dealt with a lift before and don't know what the PO has done. I do know that the steering arm had a sticker on it stating that you need the correct pitman arm ( it was a warning sticker ), so what would be the correct pitman arm?? Thx in advance!
