Suggestions to remedy a loose Benchmade AFCK's axis bar?

Skip this first paragraph if you know what an axis lock looks like and how it works. If you aren't familiar with how an axis bar looks, it has a flat piece behind the head on each side that serves two functions; the spring wedges between it and the head on the bar, and it butts against the handle to prevent the bar from passing through the handle to one side. Normally, the heads are tightened down enough so that there is just a small amount of room between the handle and the flat pieces, the idea being too tight and there is too much friction from the flat pieces rubbing on the liners, but if there's too much space, then it's harder to unlock by pressing back one side of the bar because the bar goes crooked.

With most axis bars, the heads screw on. Here's what a 710's looks like, for instance. You can see the male part in the middle (essentially the bar has a threaded pin on each side), and the surrounding part screws on:

The nice thing about the design is you can tighten it to your preference. Every Benchmade I have is like that with the exception of this AFCK. Notice there is no middle section, but instead the head is one piece:

I thought maybe it screwed on but without the hole/threads going all the way through, so I tried twisting it off with a good deal of force even after boiling it in case it was loctited on, but it didn't budge. The whole thing seems to be one piece. That wouldn't be a problem if there wasn't a huge gap between the flat pieces and liners. This is what it looks like with one flat piece flat against the liner (arrow pointing to the gap):

and as a result it goes very crooked when unlocked from one side:

It makes it feel sloppy and is harder to unlock with a finger. Has anyone run into this problem and fixed it, or have any suggestions given the pictures? Thanks in advance.

Solved it. By adding thicker washers, the gap between liners is widened, reducing the gap between liners and those flat parts on the axis bar!
