If you have any fabrication skills, you can make your own panels out of light gauge steel. the rollers can be bought at any good hdw. store . they are cabnet drawer rollers. I cut mine out of some salvaged sheet metal off an old forced air furnace, complete with louvers in the RH panel. The grill is made from a screen door protector panel and rabbit fence with an automotive welting triming it out. I have a friend that is making me a hood madallion with the eagle clenching a Deere in his claws.If you are looking to be production correct, the sources that have been listed by others provide the "correct " parts, but they are pricey. Depends on your aspirations and budget.
