Replacement Windshield Cowl

Removed screw cap

It is difficult to remove the screw covers without marring the cover or the nearby cowl. Hopefully these pictures help show where the tabs are located. Luckily, the windshield kit I bought came with all new plastic fasteners.

Removed windshield wiper

One nut under a dust cover attaches the windshield wiper. The spring-action of the wiper makes it difficult to remove from the threaded stud, but it comes off easily while holding the wiper straight.

  1. Excellent tutorial!
    I am about to change mine and it made me pretty confident to proceed

    thank you

    1. I posted some updated photos just now. The fitment isn’t perfect, the rubber isn’t sealing against the curve of the windshield.

      1. Thank you! very helpful. I may be wrong, but NA01-50-792A appears to be the part number for the rubber gasket part itself. Since my cowl isn’t cracked (but the rubber seal is totally shot) I might try one of these.
