I used tie wrap mounts that I bought from a teletronics supplier
http://www.sandman.com/pdf/Page58.pdf Spray paint them black or what ever color you want and pop rivet them in place. Then pass a tie wrap through and they all but disappear. I prefer the Model SWI 4Q. The gray tie wraps they sell work great for anchoring braided ss
oil cooler lines. Their color blends in with the ss.
