Shim or not to shim: 26.8 to 27.2?

If you can get hold of some shim stock from any machinist supply store or general millwrighting buddies you will be set. They come is sheets 12"x12" in any thickness possible. You can use a nice long section all the way down the post. No movement anywhere.
If you have to you can order it from Mcmaster carr but its kinda pricey.

Also I just checked Amazon, they sell it too. and cheap
