300ex to 400 or 450R front suspension

[MOS300ex]

Ive seen the kits for the 300ex to upgrade to the 400 or 450R front shocks. Its a bolt on kit, basically relocates the top shock mount so that you can use the other shocks. Has anyone used one of these? I know they make them for the other brands. I think its a company called Diamond Motorsports or something along those lines.
