who sells the heavy duty YJ steering box cap tapped for ram assist?

[rondo]

Long story was a few yrs back I hired a guy to do ram assist steering for my YJ. He tapped the cap and needless to say it blew up after a couple trips off road. He did a lot of sloppy things but that's for another day.

I read something about a company that sells heavy duty replacement caps with the end tapped that is a bolt on but i can't recall who it was. anyone remember?

thanks!
