Reached out to a company today after i saw they made some HD uniball UCA's for the WK. They're in the process of joining the forum but I thought you guys would appreciate a preview of what they have to offer (http://www.american-motorsports.net/?page=home)
I've recommended a minor design tweak. Looking forward to them joining up and discussing their arms and anything else they have in mind for the XK/WK platform.
