Spark plug wire holder question?

I couldn't find ones like what I wanted so I ended customizing some to make what I wanted. I used these: https://m.summitracing.com/parts/spe-4631

And I took the brackets from a set like these:

I cut the brackets down so they weren't so tall and drilled a new hole in them. Then I even painted them back wrinkle to match my valve covers. Next I mounted the other clamp down separators to them and the entire assembly attaches with a valve cover bolt for a clean look.
