something i came accross at trinity tech talk from Josh Cyrul's thread .....
"Locked front diff - less steering, easier to drive but acts the same as a one-way when you are on power - just has brakes and isn't as out of control as a one-way is. They are making a solid diff for the car - Don't just smash your diff down. The gear will bolt onto the solid diff like the gear bolts on the one-way.. "
hope that sheds some light on the matter. and maybe Baker was referring to a prototype or fabricated solid diff in the Reedy and Nats rather than simply cranking down the diff bolt....
