Header Help

[diplo 10]

I was finishing up the brake lines tonight when I noticed that my pitman arm was hitting my drivers side header when I turn the wheel to the left. It stops and if I bump the wheel harder it actually shakes the engine. I have a 302 crate engine with try y headers. It is a power steering car but I don't have all of that hooked up yet. Everything came as is when I bought the car. Any help on how to fix the problem??? Thanks
