If you need a wiper blade replacement for your 1991 Lotus Esprit SE, do not believe that you HAVE to settle for a wiper blade replacement that is TOO NARROW for your wiper bow! I even ordered a wiper blade replacement from a LOTUS parts dealer and was sent one of these VERY narrow wiper blade refills for $17 plus shipping and handling!! After I received it and tried to install it, I called the LOTUS parts place. They advised me to BEND my original Lotus wiper bow in from the sides to fit this VERY narrow wiper blade refill!!!! I told them that I did not want to do that because I was afraid that it would end up damaging the windshield on my Lotus Esprit! So I started looking around and I found a wiper blade refill that is the proper width--it is a ANCO U-24R and I found it at Autozone. It was a tight fit to thread the wiper blade refill through the bow but it fit perfectly and tightly! I bought TWO wiper blade refills in the ONE package for about $5 (five dollars). Each one of these two wiper blade refills had a metal clip on it. I took the metal clips off of both and when I installed the wiper blade refill into my original Lotus wiper bow, I put BOTH clips to hold the wiper blade refill tightly in place on the wiper bow. I put one on EXACTLY AS THE INSTRUCTIONS SHOW--BE SURE TO LOOK AT FIGURE 1 OF THE INSTRUCTIONS FOR THIS! Then I put the second metal clip at the very end of the total wiper (the free end which is at the passenger side when the wiper is OFF). Make sure that the center projection of each clip fits into the holes (small depressions) on the wiper blade refill! This beats paying the $120 I was quoted for a new Lotus wiper blade and bow! Good luck!
