John- This is from memory, so correct me if I'm wrong here. I think you may
have it backwards. With the curve toward the motor, the "practical" way, it
creates a more _positive_ camber. /  \  (Thank you, Pete)  I looked at my
tracing of the fulcrum pin again and it is 1/4" difference not the
previously stated 3/8". If you orient the fulcrum pin away from the motor,
this will push the bushings and upper arms away from the motor as well. That
will move it toward negative camber. \  / That would require _more_ shims to
match your original setup benchmark.

In my haste of tracing the fulcrum pin, I forgot to identify the
corresponding lines of the bushing shafts. Please correct me if I'm wrong!
