72 steering box

Hey all who read this
Having issue with my 72 Demon. I have a 2537349 manual steering box, new pitman arm which I checked same as one I removed. I centered box installed arm and it is offset to right. I have to have tie rod ends all the way in on one side and out on other to get wheels straight. On center knuckle is not center front to back but offset to right.
Also, maybe motor mount problem, but center link hits oil pan and pitman arm bolt hits starter.
thanks for any help
Jeff
