Call up the best Subaru/Toyota parts counter in your area and walk through all the shims you need by thickness - they can give you the corresponding part number. It’s frustrating that the thickness is not just in the part name but not much we can do about it.
As a note, I was surprised that about half my shims were borderline too loose after 117k miles, one pair was out iirc, worth putting in the effort if you’re hunting for those last tenths of a pony. Injector cleaning was probably worth more though.

I'm surprised the gap was "loose". With wear, I would think that recession of the valve would have decreased the lash.
