Dead steering issues!!!

[69camarokid]

So i had about 4 inches of dead steering on center with my old steering set up. So i picked up nad installed a new cpp 500 series steering box and pitman arm.

But i still have the 4 inches of dead steering! ugh. Once im out of the dead zone the steering is much better. So im assuming the dead area is being caused by something in the coloum perhaps?
any ideas on the issue and ways to check / fix it? thanks
