Crooked K-Member

Ok, I have looked and cannot find any threads related to this issue. I am not saying they are not there, I just can't find them. I have a 1973 Swinger that I just put new wheels and tires on. Upon getting them installed, I have found that the front-end sits off to the left more than the right by a considerable amount. I removed the factory bolts and put a set in that did not center the sub-frame like the originals. I then utilized a frame machine at work and pulled the k-member to the right. It is still offset enough to see with the naked eye. This is my first venture into Mopar cars and I am looking for some advice. Is it ok to slot the holes and slide it to the center? I am nearing this method with speed as spring is almost upon us and I want to drive the new rig. Any and all help is greatly appreciated.
