Ideas from those of you who built your own hold downs

I would also like to put the low profile, molded splash guards on my factory dual wheel fenders, I found some but I don’t want black. You would think they would make them in custom paint colors like they do for auto’s. I have been trying to find grey with no luck.
It you look at the arrow I drew on the photo it looks like “mud / water” could actually sling
over the top of the t/c hold down bars even if I did decide to hang mud flaps from them as was suggested earlier.
