Simple flag pole bed mount idea

This weekend i whipped up a couple flag pole mounts for the ol' taco.
Made from materials i found in the metal bin at work...aka free!
1/8" thick steel plate with 1-1/4" holes already in it(anchor bolt template)
1" stainless steel pipe, cut to 44" long.
It's pretty straight forward. When the pipe slides straight down through the hole it's loose, but with the pipe is pulled on an angle it sits tight in the hole. I added a 3" lag bolt to the bottom of the bed that the pipe slides over to prevent any movement.
The flags are held on with zip ties and 3/16" holes drilled through the pipe.
It so far can handle 130km/h (80mph) with no play.
I still have to grind of any sharp edges and paint them black but just wanted to show some pics first to give an idea.
Cheers.
