One item of consideration when comparing the two airframes (235, 320/360) is the location of the horizontal stab. and elevator. 

 

Although they may be of the same size on each airframe, keep in mind the distance of them from the firewall or from the pilots position is different.  The 235 airframe, although similar looking is shorter in the tail cone area.  This may not be readily apparent until the planes are sitting side by side or near each other.  The "tail feathers" on a 235 are farther forward than on the 320/360.  As a result, it is likely there will be some control surface input differences which in turn may require different trim tabs.
