Sounds like a good idea Bob, why dont you go ahead and build it and use the diff
for steering with the exising brakes. It would probably not be as effective as
the planetary differential steering in a Cletrac bit I believe it would steer
I am not familiar with the hand clutch you mention on one axel. I have a WC but
I believe it has individual hand brakes. If you decide to impliment the clutch
plan I think a strategically placed bolt would lock the diff.
