You can put a 20 inch blade on the drivers side.  Someone mentioned this a while back and I find that it works well especially since my passenger side blade is off right now.  thankfully it is winter and I do not need wipers much now.  I foolishly went to readjust the arm position on my wipers last month and the passenger side stud broke while loosening the nut.  Just one more reason to tear my dash out soon.:>)
