This is a custom CAD designed, cnc plasma cut panel that attaches to the factory fender of an 81-88 chevy C10. This panel covers the factory holes to smooth out the inside of the fender and gives it that custom look and cleans up the inside of the engine bay. This panel can be screwed, glued, bolted or welded on depending on what works best for your application. These panels cover from the front of the hinge spring mount all the way to where the core support mounts. The panels are made from a heavy 18 gauge sheetmetal for superior quality. The panels come as unfinished raw steel. Mounting and finishing will be up to the installer. There is a hole located at the bottom of the panel that is for the lower core support mounting hole. This is for a set of panels. One for the driver and passenger side of the truck. As you can see from the pictures, once the panel is color matched to the fender it becomes nearly invisible and has a very smooth factory look. If you have any questions please ask before ordering. All parts are made to order, so all sales are final and unless the panels are damaged or lost in shipping there are no refunds. You can see all the different steps in the process and the final look in the pictures. As with any custom aftermarket piece there may need to be holes drilled or very minor modifcations to suite your personal vehicle. Just like all of the parts we sell, these are PROUDLY MADE IN THE USA!
