plastic D-rings

I have a 22 year old Current Designs Equinox. There are six plastic D-rings that are used to strap down the back hatch and two of them have broken so they probably all need to be replaced.



The D-rings are about 1 1/2” long and about 3/8” in diameter. There are two plastic parts that loop around the D-rings and are attached to the boat with rivets at the other end. The rivets are placed approximately 5/8” apart. It is this thin plastic connector that breaks, not the D-ring.



I have done a fairly extensive web search for them with no luck. Does anyone know where I could find these D-rings and the connecting parts?



Thanks.
