Here's something simple I just whipped up! I hate the stock Chevy dust caps on the rotors. They won't work with how I want the look. I found some trailer caps (kinda look like early style caps) at a shop and grabbed 4 of them at $2 a piece. A chrome guy owed me a little favor, so I had him chrome these to match the wheels unlike the stock zinc coating (stock on the left new ones on the right)
Now the new ones are too small to fit into the rotor. No problem! I cut the lip off the factory one
and slid it onto the new cap (it fits snug too)
a few tack welds around the perimeter and Bam, looks like new/old!
