Patrick,
This type of situation in mixed size volumes can be alleviated somewhat by double rebuilding with manual fail/unfail operations. However, if you're getting bigger replacements in a mixed size volume this situation can be difficult to avoid.
See if NetApp or your will loan you a shelf of 36's for a weekend. Then you can build a new temporary volume and copy your data to it. Then blow away and rebuild your existing shelf as permitted by the physical disks (36GB Parity, 3x36GB data, 3x18GB data - I assume your hot spare is a 36). Then copy your data back and return the loan shelf. Voila! An extra 68 odd GB will appear.

I have a Filer 720. Is there any way to resize an existing volume short of re-creating it?
Originally the volume started with all 18 GB drives. Overtime, as disks failed, they were replaced with 36 GB drives. So now we have some 36 GB drives that are only half used. See below:
