Tailgate strengtheners are all EOL??

So I followed more than one post over to another forum, and searched everywhere here and can't find what is being done now on tailgate strengthening? I ordered the Toyota TSB parts and they are EOL, it looks like the others who were making them are no longer? I'll make my own if I have to, but I realized a long time ago that buying a proven setup saves a lot of time over making something twice! Any leads, anyone have something laying around that they haven't installed?

 

Thanks. I've searched and ready plenty of threads. I am capable of making my own setup as my home garage has a mill, big welder, plasma cutter, etc., I just dont really want to. I prefer to spend fab time on fun stuff htat I can't buy so I am looking for a lead on anyone that is still selling a bolt in kit. Plus, if I fab it myself, the tailgate will probably support another Taco, but be too heavy to lift it off. I definitely wont need any hose clamps.....
