I made some tie-down rings similar to
this . Instead of using metal flat strap, I used a short piece of black 1 inch nylon strap and a d-ring. I ran the nylon strap through the ring and doubled it back on itself. Then I burned a hole through the strap for the fender bolt to go through, and I cut the strap to length with a hot knife so it wouldn't fray. I also added a washer, painted black, over the strap to hold it more secure. They were simple and cheap to make, and they look and work great.
