Mark,

The easiest way to do this is to do something like set the possition of 
one to be UC and the other to be LC. you can also push them farther 
apart by using OFFSET to move the upper one higher and the lower one lower.

You might also try POSITION AUTO, but if you use BUFFER this will not help.
