This is a great inexpensive way to cover up your unsightly wiper motor cover. Made of a high quality acrylic material. Available in Satin Black, Black Carbon Fiber, or Chrome. You can put a logo on or leave blank. Simply lines up with your wiper motor top mounting bolts. There are 2 holes depending on if you have a 78-83 cover or an 84-88 cover. No drilling necessary on 84-88. The wiper motor cover does not include the locking nuts to hold it in place (reuse yours). Easy to install. Modifications are needed to mount it for 78-83. Put the passenger side on the bolt. Move the wiper cover up and down to leave a mark. You have to drill 1/4" hole 1/2" over to make it fit the 78-83 Wiper motor.
