I think when you asked me this I misunderstood.  Ascii picture
follows

               -------------------
               |<------ C ------>|
              =====================
              =====================
               |<------ A ------>|
               |                 |
               |                 |
               |      (   )      |
               |<------ B ------>|
               -------------------

If "C" is your dimension that's "small" by 30 thou, you're
OK.  If it's "A", or "B", you're not so OK.
