Just thought I share this here,
I'm not sure if there's any modern Lexus models that uses 20" and 21" blades stock, but after going through the Toyota spreadsheet of wiper blades I've discovered that current Tacoma models do use 20" and 21" blades (technically they are 19 3/4 AND 20 3/4)

BLADE:
RH: 85222-04040 (~$20)
LH: 85222-04040 (~$25)

Rubber Inserts: (~$10/ea)
RH: 85214-0E140
LH: 85214-0T040

the replace-ability of these rubber inserts make them better than most on the market and cheaper.

 

Good addition to these options:

(Might as well have stuff cross-linked for future reference.)

 

I've looked into those, Sadly, those aren't sold here in Canada, and it seems to me that they are discontinued from Toyota. Now Toyota are pushing these replacement blades that you can't replace the inserts for them, which kinda sucks...
