Re-Foam Kit for ML Monolith Available?

Does anyone know if a re-foam kit is available for the Martin Logan Monolith Woofers? I have a set that I would like to restore.
Many thanks. I wasn't sure how much variation there may be with the outside diameter, design of the roll, and thickness or pliability of the material.
If they don't have what you need, try Speakerex in Florida. They, from what I just saw on, carry a much larger line of replacement parts.

Good luck,
Thanks again all,
I knew I could count on the Audiogon group - everyone always comes through and is always so helpful.
