Part Number: MS264
Name: COE Fender Pads
Description: For the first time since discontinued by General Motors over 50 years ago, we are marketing two pair of front fender pads for the Chevrolet and GMC "cab over engine" (COE) truck. Many, many hours creating the curved mold results a product that will fit just right to the correct position on the fender.The visable grooves in the surface are just like the original. Until now this was about the only item that could not be located for the very popular COE truck. They are attached to your fenders with windshied sealing glue that you can obtain from your local windshield installer.
Price: 169.00
How Item Sold: Pair
Fits: 1947-55 COE
