Perhaps you should read the following letter I sent you.  Your response
is quoted.......

This is not a battle, nor is it a game!  My premise was right on the
money to compare what was being discussed.  What I was trying to say
that was obviously lost on you is that you cannot make a blanket
statement about something like AWD with out a controlled test!  On my V8
if I got the h*rd on to do it I could make my car RWD.  Trust me on
this.  I can tell you a few things for certain, if you really wnated to
do this$$$$$, can promise that one would find a way to make it work.  It
might be very complex, but it could be done.  Disagree all you want(I
know that you will).<<<<<<<<<

Hmmmmm.....I hear the inconsistancy.
Again it is a Pi**ing contest.  I personally don't like it but if you
call me ion it be sure of what you previously said.
