If you have a HEMTT A4 with the bolt-on style wiper blade, NSN 2540-01-262-7708, you’ll need to upgrade when changing blades.
The first time you change to clip-on blades, NSN 2540-01-482-2300, you’ll also need to upgrade to the new wiper arm, NSN 2540-01-626-2374. You’ll find this parts information in TM 9-2320-326-13&P (IETM EM 0288, Dec 15).
