Some kind of wedge to level retaining wall capstones?

I've built a small retaining wall, and I'm trying to set the capstones. I'm not a pro, it's a small wall, but once the capstones are in place it should look great. However the bricks are not perfectly level in every direction. There are miniscule variations - I'm talking millimeters at most.

The capstones need to be perfectly level, and this should conceal any of those variations. Question is what can I use to adjust the capstones to get them level before setting them with adhesive? Imagine with wood in a door or something, having small wedges to tweak the position of something. So the same thing for concrete blocks. Thank you.

If you set the capstones with mortar, that will allow you to adjust for the variations while placing them.

As an aside, it is a retaining wall, not a piece of furniture. You seem to be going overboard in the pursuit of perfection if you're niggling over a few millimeters of difference.

If this a segmenrtal retaining wall, you should NEVER use mortar or grout, just as you never have a concrete footing.

You can use 4 generous dabs of a silcone adhesive to hold the caps in place. If you are really fussy, you can also put a few grains of sand on top the block (just enough to level it) and then apply the silicone. THis willow the wall to flex as it is intended to.
