Where to find TT bar end plugs

Looking for those cheap plastic plugs that I can put at the back of my tt bars with a hole for the cabling to go through.

Does anyone know of any cheap black ones with a hole to let cable housing through? Trying to conform with the rules on plugs and bars…

I have the standard 22.2 clamp fit as well

Here is an example of Luke Mackenzie’s plugs at Kona this year for reference:

Thanks for the help!

I would just find a standard plug that fits your extensions and drill a hole in it. I’ve done this and it works well.

I didn’t drill a hole in mine but I did just take some regular bar end plugs and it fit pretty well with some tape around it (to make it a tighter fit).
You can use some wine corks, drill a hole in that, and sharpie them black, if you are really cheap.
