Best way to fix this?

[64stpside]

I installed a cpp front sway bar on my 64 c10 and the nut and stud on the bottom of the pitman arm needs about 1/4-3/8 in to clear the bar. I have 2 scenarios as to what might have caused the issue 1. I installed pwr steering using captainfabs bracket kit and hope i didn't set the gearbox down to low or 2. my pitman arm not up far enough. As far as fixing the issue, I'm leaning on cutting down the round spacer tube that's in-between the bushings on the endlinks and spacing the frame mounts to drop the swaybar to get the clearance. The 3rd pic is a closeup of the pitman arm. Do I have to many splines showing or is that as high as is will go? What do you guys think?
