These are NOT your cheap, $30.00 imported tail light fillers! These are hand crafted by Bob Grant, owner of the famous Grant Kustoms. These fillers have the compound curve that flows with the shape of your bed.
You will not find a better set of Fillers made by anyone else! They might be expensive, but the labor you save, and not having to pile up a 1/2" thick layer of bondo makes it so worth the extra money.
