Need '87 5000 Q owners manuel

[Bob Mansker <oscargum@datasync.com>]

Need a 87 5000S Q owners manuel if someone has one. 
Can someone please explain my Quattro control knob on my 87 5000Q.??
In the up position it has no number.  Next position is "1" & then "2".....
What does this all mean???
On the side I got some interesting comments on my Rack leak.  Some said not
to use the new "BarLeaks"
for power steering (new product).... One recomended "K & W"... Guess I will
wait for more comments.
Thank again,
