I don't know if it is a recommended way to do this but you can make those washers any size you want by lapping them properly. If you needed one .25 start with the .28, if you want one .30 start with the .38. Using a very fine sandpaper, I would do this with 1500, and putting oil on the paper on a known flat surface, the selected shim is rotated in a figure 8 pattern. Object is an even wearing of the metal by distributing the uneven forces evenly. (boy I hope I said that one right)

I have lapped stuff this way but not those particular shims.
