What ever is wrong with the steering side a file will not fix it
Be sure the pitman arm and idler arm are the same length

With the steering centered please measure the height difference between each end of the center link. Car needs to be at ride height

I'll get a measurement hopefully in the next day or so and I've read more on the pitman arms and apparently, the manual and power are the same so I'll try putting my other one from the power box on for comparison.

I measured the steering arm differences and they are only 1/8" difference from drivers side to passenger side. I also just noticed that the pitman arm now hits the header tube as well. I'm figuring at this point it has to be either the pitman arm or the pst steering box.

I installed a shim on each of the top steering box holes and the pitman arm and steering rod bolt both clear now, but the centerlink still isn't parallel with the ground. Is this a problem? I don't want to add a ton of shims to correct it if it won't cause any issues.
