Note: The cover is an imported item, lightweight, with a limited quantity available. There may be very small imperfections in the powder coat, not visible from 5 feet away.  Because of the limited quantity, these are Not able to be returned or exchanged.


These are also available with a Chrome Cover, which you can see HERE, a MCF Cover, which you can see HERE, and No Cover, so you can use your factory Ham-Can Cover (or no cover at all, or a cover you design).  See the No Cover 828 HERE.
