The fix seems pretty simple. Don't buy this box until they fix the design. I've installed a few of these, and the box is great, but the alignment and splining at the pitman suck. The factory rag joint shouldn't be at any angle, much less enough to cause binding. ONE vendor saying "call me for a magic bullet" doesn't breed a lot of confidence.
Until Borgeson can figure this out, I'll stick with Firm Feel and possibly be designing my own rack system with a custom spindle for my next project.
