Passenger side is an Anco N-22R refill.
For the drivers side I buy an Anco N-28R (for Mercedes single wiper cars) and cut it down with a razor blade. The N-28R comes with snap-on end caps that hold it in place, you'll just need to make 2 new "indents" similar to ones that you cut off on the new end.
Under $10 and you even have an extra 22" refill for the passenger side.
