Ah yes, I see what you are saying now Chris.
But nope. I wrote the original wiki on Schumacher a few years ago (asking Robin Schumacher to check facts along the way), and I put in about Cecil making the ball diff, and development of the CAT 4000. However it's since been modified multiple times by all sorts of random folk so I'm not sure we can count good ol' wikipedia as a trusted source source on the 2wd buggy.
I really hope it's coming though
